Embodiment 1

[0022] Embodiment 1: A kind of incision dilator for thoracoabdominal surgery, see figure 1 , figure 2 with image 3 , the left half body 1 is respectively provided with shaft hole A' and shaft hole B'; the right half body includes the right half body front assembly 2 and the right half body rear assembly 3; the right half body front assembly 2 is provided with shaft holes B" and C ", the shaft hole C" is a bar-shaped shaft hole; the right half rear assembly 3 is provided with shaft holes C' and D'; a double-hole connection block 4 is also provided, and the double-hole connection hole 4 is respectively provided with shaft holes A" and Shaft hole D".

[0023] The shaft hole A' and the shaft hole A" are connected together by the pin A; the shaft hole B' and the shaft hole B" are connected together by the pin B; the shaft hole C' and the shaft hole C" are connected by The pin shaft C is connected together; the shaft hole D' and the shaft hole D" are connected together by the p...

Embodiment 2

[0031] Example 2: see Figure 8 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the first support arm and the second support arm are respectively length-adjustable support arms, which are fixed by locking pins 11, and the locking pins 11 Because the components are not often adjusted, it only needs to be adjusted according to the needs, and there is no need to adjust again during the operation.

Abstract

The invention discloses an incision expander for a pleuroperitoneal cavity operation, which includes a left half body, a right half body and a double-hole connecting piece, wherein the right half body includes a right half body front assembly and a right half body rear assembly; the left half body, the right half body and the double-hole connecting piece form a controllable four connecting-rod structure by four pin shafts; the shape of the four connecting-rod structure can be changed when a handle is pressed, and the four connecting-rod structure is stable when shaped like a triangle, and an expansion piece for connecting the left half body and the front side of the right half body front assembly is at the maximum opening degree at the time. The incision expander has the automatic locking and closing functions, can be opened or locked when a surgeon exerts pressure, and can be closed when the surgeon continues to exert pressure, so that the operation is very convenient; the structure is simplified, the production cost is reduced, cooperation of all parts is reasonable, tiny parts are not involved, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of medical equipment auxiliary tools, in particular to an incision dilator for thoracoabdominal surgery that can be opened and positioned automatically. Background technique [0002] Typically, dilators used in laparoscopic surgery or other surgical procedures have some function of mechanically grasping tissue or body parts, such as jaws, fingers or hooks. Laparoscopic surgical instruments must be inserted into small orifices formed in the body cavity. These orifices are between 5mm and 12mm in diameter. When using mechanical manipulators, the jaws etc. are usually quite small so that they can be inserted through the aperture. Consequently, the surface area of ​​the mechanical manipulators at their grasping ends will be rather small, which causes considerable stress on the body part at the grasping ends. This can lead to accidental trauma or tearing of body parts. Also, larger laparoscopic devices can be...
