Definitions

  • the present invention relates to a medical device that assists in the gripping, locating and suturing of severed tendon ends.
  • the device aids the gripping, locating and suturing of severed ends of flexor tendons .
  • Tendon repair can be performed using a local anaesthetic, a regional anaesthetic or a general anaesthetic.
  • the invasive nature of the operation means there is increased risk of bleeding and infection during the surgery. Additional risks include the formation of scar tissue which prevents smooth movements and adequate tendon gliding, and partial loss of function involved in the joint.
  • the devices currently used to allow the surgery to take place can themselves cause damage to tendons, resulting in the described problems and damage.
  • a yet further object of the present invention is to provide a medical device that is disposable in nature.
  • a tendon suture aid comprising a pair of tendon gripping means and a position adjuster means, wherein the gripping means are able separably to attach to the adjuster means, such that they are held substantially parallel to each other, and such that the position adjuster means can be lengthened or shortened to widen or lessen the distance between the two gripping means .
  • the gripping means is a syringe clamp.
  • the adjuster means is a clamp.
  • the syringe clamps comprise a stem section and a tip section.
  • the stem section is covered by a sleeve section.
  • the tip section may comprise a needle.
  • the tip section is provided with one or more protruding elements which extend substantially perpendicular to the syringe clamp.
  • a detachable tendon band is provided which is able to attach to the protruding elements, such that the band at least partially surrounds the tip section of the syringe clamp.
  • the tip section of the syringe clamp is shaped such that the lower profile fits the profile of a tendon.
  • the position adjuster means is provided with a ratchet mechanism.
  • the ratchet mechanism is a thumb wheel.
  • the action of turning the thumb wheel in one direction will result in the position adjuster means shortening, and the action of turning the thumb wheel in the opposite direction will result in the position adjuster means lengthening.
  • the needle is made of stainless steel .
  • the components of the position adjuster means and gripping means are made from one or more from a list of polycarbonate, polysulfone and silicone.
  • a method of using a tendon suture aid as in the first aspect wherein the gripping means are used to grip the free ends of a damaged tendon; the gripping means are then attached to the adjuster means, such that the gripping means are held substantially parallel to each other; and the position adjuster means are then used to draw the gripping means and the free ends of the damaged tendon closer together.
  • Figure 1 shows the components that make up a syringe clamp
  • Figure 2 is a diagram indicating how the syringe clamp and the position adjuster clamp can be combined to provide the suture device in one form;
  • Figure 3 is a side view of the suture aid according to the present invention.
  • Figure 4 is a front view of the suture aid according to the present invention.
  • Figure 5 is a top view of the suture aid according to the present invention.
  • Figure 6 is a perspective view of the suture aid according to the present invention.
  • Figure 7 is a diagram of the tip of the syringe clamp according to the preferred embodiment of the present invention.
  • Figure 8 shows the sequence of events that would typically occur during tendon repair using a device according to the present invention.
  • the tendon suture aid 1 is used to locate, grip and suture the severed ends of tendon 2.
  • the tendon 2 is a flexor tendon 2 located in the hand or forearm.
  • the point of the needle 3 is inserted into the tendon 2, and the upper surface of the tendon 2 locates on the tendon profiled face of a syringe clamp tip 4.
  • a tendon band 5 is then looped underneath the tendon 2 and is attached at both ends to the studs 6 that protrude from the syringe clamp tip 4. Once the tendon 2 is held in position, the tendon band 5 is tightened around the tendon 2 by means of a syringe action.
  • the stem 6 comprises a sleeve element 7 which rises up the stem 6 using a ratchet mechanism 8.
  • the ratchet mechanism 8 prevents the tendon band 5 from slackening when the syringe actuation force is removed. This results in the tendon 2 being gently and automatically gripped to allow the manipulation of the tendon 2 during the suture process.
  • the sleeve 7 is not a separate element and the stem 6 is formed from a single body piece.
  • the ratchet mechanism 8 is removed and instead the tendon band 5 has multiple holes at each end which can be attached to the stem, such that the band 5 can be tightened or loosened by attachment via different sets of holes.
  • the tendon 2 is securely held by the tendon needle 3.
  • the tendon band 5 prevents the needle 3 from being withdrawn from the tendon 2 during manipulation.
  • the needle 3 also prevents the tendon 2 from distorting as the suture is applied and prevents the ends of the tendon 2 from buckling and bunching up as the suture is tightened and several tendons end 2 bunch up together.
  • the sleeve 7 of the syringe clamp 9 can be attached to a position adjuster clip.
  • two syringe clamps 9 are used to find the separated tendon ends 2 of a severed tendon and then, once the severed ends 2 have been located and held securely, the two syringe clamps 9 are attached to the position adjuster clip 10.
  • the position adjuster 10 comprises two holding sections 11 into which each of the two syringe clamps 9 can be fitted.
  • the holding sections 11 are held at a fixed position apart by a positioning section 12 that joins the two together.
  • the positioning section 12 is able to act as a screw in the preferred embodiment, and comprises a thumb wheel 13 at one end.
  • the thumb wheel 13 when turned results in the holding sections being moved closer together or further apart. Therefore, when the syringe clamps 9 are placed in the holding sections 12, their distance from each other can be changed by turning the thumb wheel 13. This allows a surgeon to have very accurate control over the tendon ends 2, pulling them together in a careful and controlled manner. This makes the operation of flexor tendon repair much simpler to perform than in the prior art, and results in much less tendon damage, as there is less dragging, pulling and lengthy clamping of the tendon ends 2.
  • the present invention provides a number of benefits over the prior art, in particular with regard to the control and delicate manoeuvring that the device allows.

Abstract

Dispositif médical destiné à assister la saisie, la mise en place et la suture d'extrémités de tendons rompus. Ledit dispositif apporte en particulier une assistance pour la saisie, la mise en place et la suture d'extrémités rompues de tendons fléchisseurs, ce qui entraîne une réduction des lésions subies par les tendons pendant l'opération chirurgicale, étant donné que les extrémités du tendon sont soumises à moins de frottements, de traction et de longs moments de serrage.
