Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a retractor handle for surgery. Background Art

[0002] A surgical retractor is a tool specifically used to pull tissue and expand the surgical field of view during surgery. It is a medical device with various shapes, solid materials and strict sterilization. A surgical retractor handle is required to facilitate holding the retractor.

[0003] The surgical retractor handle refers to the component that allows the user to apply force to control the retractor movement during surgery. It is a device made of sturdy material, with fine surface treatment and easy to clean and disinfect.

[0004] Currently, surgical retractor handles on the market are commonly divided into fixed and hand-pull types. The hand-pull types have various shapes, but in actual use, they only focus on function without considering standard universality, ease of use and experience. Fixed retractors, in particular, are fixed through a complex fixing table and have many parts and are inconvenient to clean and disinfect, thereby reducing the practicality of the device. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a surgical retractor handle, which aims to improve the problem in the prior art that the retractor parts are relatively complicated and inconvenient to clean.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a surgical retractor handle, comprising a handle, wherein the handle and the hook body are movably connected.

[0007] As a further description of the above technical solution:

[0008] A reserved hole is provided at one end of the handle, and the reserved hole is used for inserting and installing a connecting rod, and a hook body is provided at the bottom of the connecting rod.

[0009] As a further description of the above technical solution:

[0010] A plurality of holes are provided on the connecting rod, a reserved groove is provided on the inner side of the handle, a latch is provided in the reserved groove, and one end of the latch can pass through the reserved hole and engage with the corresponding hole.

[0011] As a further description of the above technical solution:

[0012] One end of the latch is fixedly connected to a gear handle, and a groove matching the gear handle is provided in the reserved slot.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the present invention, a preliminary connection is achieved by first inserting the connecting rod with a hook into the reserved hole on the outside of the handle. Then, as needed, the pin is inserted into the handle so that it passes through the reserved hole and the corresponding hole for fixation. The device can be quickly disassembled and assembled, and the height of the connecting rod can be adjusted, thereby improving the practicality of the device.

[0015] 2. In the present invention, the latch is inserted into the reserved groove and rotated so that the gear lever and the groove engage with each other, thereby firmly connecting the gear lever and the handle. At the same time, the gear lever can be prevented from blocking the handle, thereby preventing an adverse effect on the comfort of holding the handle, thereby improving the convenience of the device.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1 The present invention provides an embodiment in which the handle 1 and the hook body 5 are movably connected; a reserved hole 3 is provided at one end of the handle 1 for inserting and installing the connecting rod 4, and a hook body 5 is provided at the bottom of the connecting rod 4;

[0023] Specifically, by inserting the connecting rod 4 and the hook body 5 thereon into the reserved hole 3 , the hook body 5 and the handle 1 can be quickly installed and fixed.

[0024] Reference Figure 1 and Figure 2, a plurality of holes 7 are opened on the connecting rod 4, a reserved groove 8 is opened on the inner side of the handle 1, a latch 6 is provided in the reserved groove 8, one end of the latch 6 can pass through the reserved hole 3 and engage with the corresponding hole 7;

[0025] Specifically, the connecting rod 4 is fixed by inserting the pin 6 into the handle 1 so as to engage with the hole 7 on the outside of the connecting rod 4 , and the height of the connecting rod 4 can be adjusted by inserting the pin into different holes 7 .

[0026] Reference Figure 1 、 Figure 2 and Figure 3 One end of the latch 6 is fixedly connected to the gear lever 9, and a groove 2 matching the gear lever 9 is provided in the reserved groove 8;

[0027] Specifically, when the latch 6 is inserted into the reserved groove 8, the gear lever 9 is rotated to engage with the groove 2, which can fix the latch 6 while preventing the protrusion of the gear lever 9 from blocking the handle 1 and affecting the comfort of holding it.

[0028] Working principle: Before using the device, first insert the connecting rod 4 with the hook body 5 into the reserved hole 3 on the outside of the handle 1 to achieve a preliminary connection, and then select one of the multiple holes 7 on the connecting rod 4 according to the actual needs of the operation, and insert the pin 6 into the handle 1 so that it passes through the reserved hole 3 and the selected hole 7 to complete the fixation. This design can quickly adjust the height of the retractor to adapt to different surgical scenarios and operation requirements. When changing the height, pull out the pin 6 and reselect the hole 7 to insert it, thereby improving operational efficiency and convenience. By rotating the pin 6, the gear handle 9 on it is engaged with the groove 2, which can fix the gear handle 9 and the handle 1. At the same time, it can also prevent the gear handle 9 from blocking the handle 1 and affecting its comfort when holding it. The detachable structure is convenient for cleaning, disinfection and storage.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
