Abstract
The utility model relates to a medical surgical appliance, in particular to a spreading forceps for scoliosis surgeries, which comprises a left half part, a right half part, a pair of spreading racks and a self-locking mechanism; the left half part and the right half part are articulated together by a shaft pin; the left half part comprises a left forceps handle and a left forceps neck, the right half part comprises a right forceps handle and a right forceps neck, and the spreading forceps is characterized in that the front ends of the left forceps neck and the right forceps neck are respectively and detachably connected with the spreading racks; and the self-locking mechanism is connected between the left forceps handle and the right forceps handle as well. Since the spreading forceps adopts the detachable spreading racks, spreading racks with appropriate lengths can be mounted according to the size of a surgical wound; moreover, because the connected handles are provided with movable joints, the heights of the forceps handles can be conveniently adjusted after the spreading racks cling to the inner flesh wall of the surgical wound, and therefore the spreading forceps has more operability and flexibility in the process of surgery.
Description
Technical field
This utility model relates to a kind of medical science surgical instrument, especially a kind of pincers that strut that are used for the scoliosis operation.
Background technology
Scoliosis is meant that one of spinal column or several sections depart from midline of body on coronalplane, to the side bending, form a deformity of spine that has radian.It can reduce the cubical content of thoracic cavity, abdominal cavity and pelvic cavity, also can reduce height.In treatment, whether the patient of few what 10 degree of lateral bending only need do tracing study has and continues to worsen phenomenon, and 10 degree then must be with intensive corrective therapy to the patients of 40 degree, and every three months does X-ray examination, to confirm therapeutic effect.Surpass the patients of 40 degree, must carry out cardiovascular and pulmonary function test, as when influencing cardio-pulmonary function, then must correct with surgical operation.When carrying out the scoliosis operation, need to cut a bigger wound, and strut this otch to strut pincers.Traditional pincers that strut only are made up of left and right sides caliper, a self-locking mechanism.The front end of caliper is fixedly connected with and struts tooth bar, is used to strut operative incision, but tooth bar is shorter usually, and the cut sides that struts is less, and fixedlys connected with caliper, can not change; When carrying out the bigger operation of this class operative incision of scoliosis, the common pincers that strut often enough fully do not strut otch, often need up and down two to strut the work that struts that pincers are finished otch, have not only increased operating time but also more loaded down with trivial details.The common in addition pincers that strut are not provided with Movable joint on front end struts connection handle between tooth bar and pincers handle, thereby are strutting after pincers strut operative incision, high and low position that can not free adjustment pincers handle.
The utility model content
This utility model is a purpose to solve above-mentioned inconvenience, provide a kind of can according to the operation needs, change the tooth bar that struts of required size, and be provided with Movable joint, strut pincers thereby can regulate the scoliosis operation that clamps the handle high and low position along the Movable joint rotation.
This utility model is achieved in that a kind of scoliosis operation struts pincers, and it is made up of left side, right-hand part and self-locking mechanism; Described left side and right-hand part are by the pivot pin active link; Described left side by a left side clamp handle, pincers neck and in a left side struts tooth bar and forms; Described right-hand part by the right side clamp handle, right pincers neck and struts tooth bar and forms; Also be connected with self-locking mechanism between described left side pincers handle and right pincers handle; It is characterized in that: the front end of described left side pincers neck and right pincers neck is connected with the middle part that struts tooth bar respectively.
Be respectively equipped with Movable joint on described left side pincers neck, the right pincers neck.
Described left side pincers neck adopts bolt with right pincers neck and being connected of tooth bar that strut separately.
The beneficial effects of the utility model are: the scoliosis operation that this utility model is described struts pincers and has adopted dismountable tooth bar that struts, and the length that can change the outfit according to the size of surgical wound is suitable struts tooth bar; And on connection handle, be provided with Movable joint, after the meat wall is fitted in strutting tooth bar and corrective surgery otch, can regulate the high and low position of pincers handle easily, in operation process, have more operability and motility.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the prior art constructions sketch map.
Specific embodiment
Referring to Fig. 1, this utility model is made up of left side 1, right-hand part 2 and self-locking mechanism 3.Left side 1 and right-hand part 2 are by the pivot pin active link.Left side 1 and right-hand part 2 are made up of left side pincers handle 11, left side pincers neck 12 and right pincers handle 21, right pincers neck 22 respectively.The front end of left side pincers neck 12 and right pincers neck 22, respectively with strut tooth bar 4 and removably connect.According to the needs of operation, the length that can change the outfit is suitable struts tooth bar 4.Also be respectively equipped with Movable joint 5 on left side pincers neck 12, the right pincers neck 22, with strutting after tooth bar 4 struts wound, the pincers handle can be along the joint 5 up and down rotation adjust to correct position.Be connected with self-locking mechanism 3 at left side pincers handle 11 and right 21 of handles of pincers.Self-locking mechanism 3 is made up of location gear piece 31, position-limiting spring leaf 32.One end of location gear piece 31 and left side pincers 11 rotatable connections of handle, the other end pass the locating slot of being located on the right pincers handle 2, and cooperate with locating slot.Position-limiting spring leaf 32 1 ends are affixed to clamp on the handle 11 with a left side, and the other end is affixed with location gear piece 31.In the operation, open up into suitable when size, utilize location gear piece 31 to match, thereby locate with locating slot on the right pincers handle 21 when strutting pincers.
Claims (3)
1. a scoliosis operation struts pincers, and it is made up of left side (1), right-hand part (2) and self-locking mechanism (3); Described left side (1) and right-hand part (2) are by the pivot pin active link; Described left side (1) is strutted tooth bar (4) and is formed by left side pincers handle (11), left side pincers neck (12) and; Described right-hand part (2) is strutted tooth bar (4) and is formed by right side pincers handle (21), right pincers neck (22) and; Also be connected with self-locking mechanism (3) between described left side pincers handle (1) and right pincers handles (2); It is characterized in that: the front end of described left side pincers neck (11) and right pincers necks (21) is connected with the middle part that struts tooth bar (4) respectively.
