Abstract
The utility model relates to a heart mitral valve expanding device for thoracic surgery. The heart mitral valve expanding device is mainly suitable for the thoracic surgery of a human body. The heart mitral valve expanding device comprises a fixed handle, a movable handle, a device rod, a pull rod, an expanding head, a kidney-shaped groove, a pull rod pin, a device seat and a device rod seat and is characterized by further comprising reset springs, screws and nuts. The two reset springs are elastic, one end of one reset spring is tightly pressed with one end of the other reset spring, and the other end of one reset spring and the other end of the other reset spring are fixed on the fixed handle and the movable handle through the screws respectively. The nuts are in threaded connection with one end of each screw, and the other end of each screw penetrates the movable handle to be clamped into the fixed handle and connected with the fixed handle through a fixing pin. The surface of the expanding head of the heart mitral valve expanding device is mellow and smooth, the opening degree can be limited, the heart mitral valve is not easily damaged in operation, and the heart mitral valve expanding device is reasonable in structural design, good in application effect and safe and convenient to use in operation.
Description
Technical field
This utility model relates to a kind of extension fixture, and particularly a kind of thoracic surgery heart Bicuspid valve extension fixture for thoracic surgery belongs to medical instruments field.
Background technology
In the torso model operation, the heart Bicuspid valve need be strutted, can undergo surgery smoothly.In the prior art, be to strut with general pincers class or long pincers class, its defective is: easily cause the mitral damage of heart, desirable surgical effect is not satisfied in carrying out smoothly of influence operation.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of structural design is more reasonable, effect good, operation safe thoracic surgery heart Bicuspid valve extension fixture easy to use and provide.
This utility model solves the problems of the technologies described above the technical scheme that adopts: this thoracic surgery heart Bicuspid valve extension fixture comprises fixed handle, flexible handle, device bar, pull bar, expansion head, waist type groove, stay rod pin, device seat, device pole socket, it is characterized in that also comprising back-moving spring, screw rod and nut, described two back-moving springs have elasticity and an end compresses mutually, and the other end is screwed respectively on fixed handle and flexible handle; Nut is connected with the threaded one end of screw rod, and the other end of screw rod passes flexible handle and snaps in fixed handle and connect with steady pin.
Expansion of the present utility model head has two, match each other and the surface mellow and full smooth.
This utility model compared with prior art has following positive effect: the expansion head surface is mellow and full smooth, and the amplitude of strutting can be spacing, and in operation was used, the heart Bicuspid valve is easy damaged not, and structural design is more reasonable, and effect is good, the safety easy to use of performing the operation.
Description of drawings
Fig. 1 is overall structure sketch map of the present utility model.
Fig. 2 is the structural representation of this utility model head.
The specific embodiment
Referring to Fig. 1-2, present embodiment comprises fixed handle 1, flexible handle 2, device bar 9, pull bar 10, expansion 11, waist type groove 12, stay rod pin 14, device seat 15, device pole socket 16, and described fixed handle 1 is connected and can rotates with flexible handle 2 usefulness set bolts 3; 16 welding of device bar 9 rear end invaginator pole sockets are fixing, and device pole socket 16 is fixing with fixed handle 1 welding; Pull bar 10 passes device bar 9 and fixed handle 1, and the rear end is connected and can rotates with flexible handle 2 usefulness 8 steady pins; The bottom that device bar 9 front ends are provided with 15, two of device seats expansion 11 is fixed on the device seat 15 with connecting pin 13; Two expansions 11 have waist type groove 12, and it is fixing with the front end welding of pull bar 10 that stay rod pin 14 is inserted in two waist type grooves 12, and two expansions 11 match each other.
In the present embodiment, also comprise back-moving spring 4, screw rod 6 and nut 7, described two back-moving springs 4 have elasticity and an end compresses mutually, and the other end is fixed on fixed handle 1 and the flexible handle 2 with screw 5 respectively; Nut 7 is connected with the threaded one end of screw rod 6, and the other end of screw rod 6 passes flexible handle 2 and snaps in fixed handle 1 and use steady pin 8 to connect, and screw rod 6 can slide in flexible handle 2, rotating nut 7, and nut 7 can be mobile at screw rod 6.
Two expansions described in the utility model, 11 surface are mellow and full smooth, and Bicuspid valve is difficult for being damaged when strutting; The heart Bicuspid valve struts needs extreme care, and operation is fine and smooth, struts must hold it and strut amplitude, rotating nut 7 is regulated its position on screw rod 6 and location, the flexible handle 2 of holding with a firm grip, under the restriction of nut 7, expansion 11 amplitude of strutting are limited, and it is spacing to reach the amplitude of strutting; Structural design is more reasonable, and effect is good, the safety easy to use of performing the operation.
After two of this utility model expansion 11 is opened, can reset under the effect of two back-moving springs 4, structural design is more reasonable, the safety easy to use of performing the operation.
This utility model is that metal material is made, and can sterilize by disinfectant solution, also can use high-temperature sterilization.
