Description

Puncture outfit with sewing function

Technical Field

The invention relates to the technical field of surgical instruments, in particular to a puncture outfit with a suture function.

Background

Minimally invasive surgery has been available for over a decade and has been widely used in the medical field, with the advantages of less trauma, less pain and rapid recovery. Many of the past open procedures have now been replaced by endoluminal procedures, with minimal invasive procedures being greatly developed and exploited, and endoscopic procedures being accepted by an increasing number of physicians and patients. Laparoscopic surgery entails establishing a working channel in the abdominal wall through a puncture instrument and performing surgery on a patient through the working channel by surgical instruments. At present, the puncture outfit is 5mm-18mm in diameter, and generally, for abdominal wall puncture holes larger than 5mm, peritoneum and fascia layers are required to be sutured to prevent incision bleeding and reduce the incidence rate of incision hernia. The traditional suture method cannot enable tissues on two sides of a small incision to correspond due to the lack of a necessary guiding and positioning means, and the ideal suture effect is difficult to achieve. The use of a fascia suture instrument for suturing requires a relatively complicated operation. Thus, the working efficiency of medical workers is affected, the operation time is prolonged, the pain of patients is increased, and the problem needs to be solved.

Disclosure of Invention

The invention aims to solve the problem that the existing puncture outfit can not suture a minimally invasive operation wound. A puncture outfit with a suture function is designed.

The technical scheme of the invention is as follows:

the utility model provides a puncture ware of function is sewed up in area which characterized in that: the puncture outfit comprises a puncture outfit and a suture assembly inserted into a puncture cannula, wherein the suture assembly comprises an outer tube 1 and a push rod 2; the head of the outer tube 1 is provided with a gear 3, the gear 3 is provided with a hook 4 rotating along with the gear, and the head of the hook is provided with a needle head 5; a suture 6 with a corresponding specification is arranged in the side hole of the needle head 5 in a penetrating way; the head of the push rod 2 is provided with a rack 7 matched with the gear 3; the rack 7 is matched with the gear 3 to realize the arc-shaped rotation of the needle head 5.

The circular truncated cone at the tail end of the outer tube 1 is internally provided with a bulge 8 matched with a clamping groove on the puncture outfit, so that the outer tube 1 can be fixed on the puncture outfit and cannot rotate; the inner part of the outer tube 1 is provided with a through groove, the push rod 2 is provided with a limit structure 9 matched with the through groove, and the push rod 2 can be fixed in the outer tube 1 and can not be pushed by a limit distance.

And a clamping groove matched with the inner part of the outer pipe is formed in the outer contour of the push rod.

The head end of the outer tube 1 is provided with a raised cylinder; the gear is arranged on the raised cylinder; the hook can rotate coaxially through a rotating gear.

The head end of a puncture cannula of the puncture outfit is provided with symmetrical holes; the symmetrical holes are of a structure with a large outer part and a small inner part, so that the needle head can be smoothly inserted and is difficult to pull out.

The invention has the beneficial effects that:

compared with the prior art, the invention has the following advantages: reasonable in design, simple structure, secondary damage when can effectively preventing to sew up has solved the puncture ware and has not sewed up the defect of function. Shortens the operation time, improves the working efficiency of medical staff, relieves the pain of patients and improves the operation quality.

Detailed Description

As shown in fig. 1-3.

A puncture outfit with a suture function comprises a puncture outfit and a suture assembly inserted into a puncture cannula, wherein the suture assembly comprises an outer tube 1 and a push rod 2;

the head of the outer tube 1 is provided with a gear 3 with a hook 4, and the head of the hook 4 is provided with a needle head 5; the side hole of the needle 5 is provided with a suture 6 of corresponding gauge, as shown in figure 1; the head of the push rod 2 is provided with a rack 7 matched with the gear 3 with a hook; the rack 7 is matched with the gear 3 with a hook to realize the arc-shaped rotation of the needle head; the push rod 2 is pressed downwards to enable the gear 3 to drive the needle head 5 to rotate; the needle head 5 is inserted into the symmetrical hole of the puncture outfit sleeve after passing through the suture position, and the suture thread end is left in the side wall of the puncture outfit. The circular truncated cone at the tail end of the outer tube 1 is internally provided with a bulge 8 (shown in figures 2 and 3) which is matched with a clamping groove on the puncture outfit, so that the outer tube 1 can be fixed on the puncture outfit and cannot rotate; the inner part of the outer tube 1 is provided with a through groove, the push rod 2 is provided with a protruding structure and a limiting structure 9 which are matched with the through groove, so that the push rod 2 can be fixed in the outer tube 1 and can not be pushed by a limit distance. In specific implementation, a raised cylinder is arranged at the head end of the outer pipe 1; the gear 3 can be mounted on the raised cylinder; the hook 4 can be rotated coaxially by means of a rotary gear.

When the puncture hole needs to be sutured in the operation, the suturing component is inserted into the sleeve of the puncture outfit, the inserting depth of the puncture outfit is adjusted according to the physical and physical conditions of a patient and the surgical type, the sleeve fixing the puncture outfit pushes the push rod of the suturing component, and circular motion is carried out through the matching hook of the rack and the gear. Meanwhile, the needle head at the front end of the gear hook penetrates through the position to be sutured and is inserted into the symmetrical hole of the puncture outfit sleeve. The push rod is pulled upwards, the gear hook resets, because puncture ware sleeve pipe symmetry pore structure is big-outside little-inside, the syringe needle can not be smoothly followed the sleeve pipe hole and withdrawed from, syringe needle and hook separation, the hook resets to initial condition, and the syringe needle then is stayed puncture ware sleeve pipe inner chamber, has the hole that the suture passed on the syringe needle simultaneously, and the end of a thread of suture just stays in puncture ware sheathed tube inner chamber together with the syringe needle. The puncture outfit and the suture component are pulled out, two thread ends of the suture thread are taken out together, the suture thread is tightened and knotted, and fascia suture of the puncture incision in the minimally invasive surgery can be realized.
