Description
This utility model belongs to medical surgical instruments, especially a kind of surgical cut apparatus, the trocar, puncture needle, convergent divergent channel, international Patent classificating number A61B17/32, A61B17/34, A61B17/56.
China's utility model patent communique the 7th volume discloses a kind of prolapse of intervertebral disc therapeutic instrument No. 49, the patent No. 90219273, authorization notification number CN2089792U, its power section is the micro machine deceleration device, power is sent on the tongue shape pressing plate through the eccentric cam on the axle, cooperate the hollow impact bar of control to move back and forth with back-moving spring, cutting part is the hollow puncture needle of fixedlying connected with hollow impact bar lower end; Its lower end is cutter, has the pin overcoat that holds the pathological tissues breach and fixedlys connected with silk braid, and the silk braid downside leaves water inlet, fixedlys connected with the lower end of shell through nipple in the upper end.The 12nd volume discloses a kind of automatic disc removal device No. 35, the patent No. 95215180, authorization notification number CN2233727Y, it includes otch, sealing ring, conduit, water inlet outlet, trocar sheath, it utilizes two-way entity Worm type cutting knife, twice of cutting rotates a circle, cut nucleus pulposus can be discharged under the worm screw effect of rotation automatically, utilize conduit as irrigator, because the caliber inflow is big, developing result is good, and the cutting knife afterbody with enucleator is connected with flexible axle simultaneously, can effectively reach the requirement of sterile working.The shortcoming that they exist is: 1, operation is more loaded down with trivial details: need guide pin, puncture needle, trocar, dilator, operation need progressively be carried out, and just can be placed on inside and outside cutting operation.2, the operation puncture channel is thicker, easily causes nerve, blood vessel injury: because interior outer cutter end is shaft-like, must be in guiding, puncture, and after expansion is set up passage and placed sleeve pipe step by step, sickle is inserted in the sleeve pipe and can cut.Thereby bigger passage has increased the danger of nerve, blood vessel and tissue injury.Part patient, nerve, blood vessel injury are often arranged in the practice and end cutting.Hematoma is arranged after the part patient cutting, complication such as nerve injury takes place in various degree.3, passage is set up in water inlet, discharge separately, has increased the sickle diameter, has increased the damage probability.Or water inlet is at interior cutter near-end, and water cycle is confined in sickle self pipeline, and cutting area is not rinsed basically, aspirate unclean, cut the suction degree a little less than.4, interior outer cutter.Far-end is column, the lateral margin opening, and during the inner cutter rotation, within outer cutter side opening plane, it is few to grasp thing all the time for its side opening blade, usually needs to get tissue by means of the vertebral pulp clamp.
It is thin that the purpose of this utility model provides a kind of needle body, and not damaged is easy and simple to handle, cuts and inhale effectively, and collection puncture needle, biopsy needle, trocar, convergent divergent channel, sickle are one, the medical rotary cut device that the suitability is strong.
The purpose of this utility model is achieved in that a kind of medical rotary cut device, it comprises power section and cuts the suction spindle body, cutting the suction spindle body is made up of interior pin 9, outer pin 10, outer pin 10 is the ducted body of both ends open with interior pin 9, one end is a taper pin sword, interior pin 9 other ends are connected with power section, and interior pin 9 is positioned at outer pin 10, and interior pin 9 is matched in clearance with outer pin 10.Outer pin 10 taper pin swords are shaped as level and smooth shape.Interior pin 9 pin swords are shaped as level and smooth shape.Interior pin 9 pin swords are waveform.Interior pin 9 pin swords are zigzag.Interior pin 9 needle points are auger shape.Power section comprises rack type ratch 2,20, ratch 2,20 1 ends are provided with bar handle 1,19, vertical setting can be inserted the circular hole of spring 4,22 in the ratch 2,20, setting prevents that the metal bar 13,21 that spring 4 is deviate from from inserting in the spring 4,22, and spring 4,22 and metal bar 13,21 constitute ratch 2,20 resetting means; Ratch 2,20 driven wheels 3,23, gear 3 is connected with the interior pin 9 of cutting the suction spindle body.Power section also comprises ratch 20, and bar handle 19, ratch resetting means, many siphunculus 6 of the insertion spool 5 that is connected with ratch 20, many siphunculus 6 communicate with the interior pin 9 of cutting the suction spindle body, tube for transfusion 7, attraction drain hose 8 respectively.
This utility model is owing to adopt the terminal taper that is, the sickle that internal and external pin combines can make to expand pin, puncture needle, sickle, bone drill usefulness, the many usefulness of a pin, and the suitability is strong.Be fit to cut the irregularity thing, smooth neat thing, cut hard thing such as file bone sex organization, not only be used for the intervertebral disc cutting, also can be used for intracranial and cut swollen, the disease of sucking blood and search material, small needle knife, pin seam hydrojet is used for sealing, separation of synechia, breaks up hematoma etc.Only need one man operation, step is easy: after internal and external pin is punctured to the target area, can begin to cut suction.Needle body is thin, almost not damaged: the water inlet of interior pin double as, cut suction and engage in this profession, reduced channel diameter, need not dilator, impassivity, blood vessel and tissue injury.Inside and outside dial is sheared organizational efficiency's height: interior pin rotation, and interior pin side is curved, exceeds the outer pin conical surface, stings that to cut thing many, and water inlet can be convenient to attraction to the target area.Manual force drives cutting, and equipment is light and handy, easy to carry, nothing has a power failure, the melancholy of electric leakage.
Below in conjunction with drawings and Examples this utility model is further described.
