Abstract

The utility model relates to a memory alloy claw-type rib blade plate, in particular to an internal fixed fracture connector that is made from memory alloy, which pertains to the technical field of medical appliance. The two sides of the girder are connected with a claw-type tackling arm, while the vertical middle shaft of the girder is made into a radian and the terminal head is provided with terminal teeth; 4 to 10 pairs of claw-type tackling arms are rolled into a snap ring; and the radian of the girder's vertical midline shaft is: 0- 90 degrees. The utility model is simple, compact and reasonable in structure; the utility model is made from shape memory alloy according to rib's anatomy of the human body and the principle of mechanics and also gives attention to various rib fracture situations in clinic, and has a better fixing effect toward many smashing fractures with a large span and a short distance; the utility model is convenient for operating, which quite conforms to the individual principle and has a low manufacture cost and saves much more materials.

Description

Memorial alloy pawl type rib blade plate

Technical field

This utility model relates to a kind of memorial alloy pawl type rib blade plate, specifically makes internal fixation synthetism apparatus with memorial alloy, belongs to technical field of medical instruments.

Background technology

Before this utility model was made, in prior art, the blade plate that is used for the rib internal fixation adopted the oval bone blade plate of encircling type usually, is to connect two epimeres by two beams, and the outside connecting ring arm of beam constitutes.This kind blade plate complex structure, manufacturing cost height, inconvenient operation; Be used for the clinical practice process of rib internal fixation, its to comminuted, large span, closely in the multiple fracture fixed effect relatively poor.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of dissection and mechanics principle to adopt memorial alloy to make according to the human body rib, take into account the situation of clinical various fractures of rib, its to comminuted, large span, closely in the multiple fracture good fixing effect; Easy and simple to handle, more meet principle of individuation, the memorial alloy pawl type rib blade plate of low cost of manufacture.

Main solution of the present utility model is achieved in that

This utility model mainly adopts in the both sides of girder 1 and connects pawl type arm 2, and girder 1 longitudinal midline axle is made radian, and its termination is shaped on end tooth 3.

This utility model pawl type arm 2 is rolled into split ring shape 4.

This utility model pawl type arm 2 adopts 4～10 pairs.

This utility model girder 1 longitudinal midline axle radian 5 is: 0～90 °.

Compared with the prior art this utility model has the following advantages:

This utility model is simple, compact and reasonable for structure; Adopt marmem to make according to the dissection of human body rib and mechanics principle, take into account the situation of clinical various fractures of rib, its to comminuted, large span, closely in the multiple fracture fixed effect good; Easy and simple to handle, more meet principle of individuation, low cost of manufacture, materials are more saved.

Fig. 3 is this utility model pawl type arm structural representation.

The specific embodiment

Embodiment during following this utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

This utility model mainly is made up of girder 1, pawl type arm 2, end tooth 3, split ring shape 4, longitudinal midline axle radian 5 etc.

This utility model adopts the both sides of a girder 1 to connect 4～10 pairs of pawl type arms 2, and pawl type arm 2 is rolled into split ring shape 4.The middle bobbin of girder 1 is according to the physiological characteristics of Different Individual and different rib different segments, is shaped on radian to be: 0～90 °, its termination is shaped on end tooth 3.

Before using,, embraces this utility model in order to grabbing earlier in frozen water support open jaw type arm 2.Periosteum separates and to finish, after the reduction of the fracture, pawl shaped steel plate is crossed over fracture line, grabs the rib of embracing fracture in subperiosteum, makes its recovery form with hot salt brine subsequently, holds and holds rib tightly, reaches fixing purpose.To preceding thoracic wall fracture of rib, select radian less, the pleurobranch wall then selects radian big; Big, comminuted to span, closely multiple fracture can select that girder 1 is long, the more blade plate of holding claw logarithm.

Claims

1, a kind of memorial alloy pawl type rib blade plate comprises girder (1), it is characterized in that adopting the both sides at girder (1) to connect pawl type arm (2), and girder (1) longitudinal midline axle is made radian, and its termination is shaped on end tooth (3).

2, memorial alloy pawl type rib blade plate according to claim 1 is characterized in that described pawl type arm (2) is rolled into split ring shape (4).

3, memorial alloy pawl type rib blade plate according to claim 1 is characterized in that described pawl type arm (2) adopts 4～10 pairs.

4, memorial alloy pawl type rib blade plate according to claim 1 is characterized in that described girder (1) longitudinal midline axle radian (5) is: 0～90 °.
