Description

Technical Field

[0001] The utility model relates to the technical field of disposable laparoscope staplers, in particular to a laparoscope component sleeve fixing structure. Background Art

[0002] The laparoscope assembly is mainly used for minimally invasive surgery, and completes tissue clamping, suturing and cutting during use. It includes the upper and lower pressure plates of the laparoscope assembly, the assembly sleeve, the nail seat assembly, the nail magazine assembly, the cutting knife assembly and other parts.

[0003] During the assembly process of the traditional laparoscope component sleeve, the lower pressure plate has a positioning boss, and the outer sleeve needs to be frictionally pressed over the positioning boss during the sleeve connection process. The installation is more laborious and leads to low assembly efficiency. At the same time, during the assembly process, debris will be generated due to the friction between the component sleeve and the upper and lower pressure plates, and the debris is not easy to clean. If it falls into the patient's body, it is easy to cause secondary injury to the patient. In addition, after assembly, the upper and lower pressure plates of the component are easy to loosen, and there is a risk of product jamming. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, a laparoscope assembly sleeve fixing structure is provided.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a laparoscope assembly sleeve fixing structure, including a pin support assembly, one side of the pin support assembly is connected to an upper and lower pressure plate assembly, and the upper and lower pressure plate assemblies are sleeved with sleeves;

[0006] A positioning boss is provided on the left end surface of the upper and lower pressure plate assemblies, and a positioning groove is provided on the right end surface. A clamping groove cooperating with the positioning boss is provided on the left end of the sleeve, and a positioning spring sheet cooperating with the positioning groove is provided on the sleeve at a side away from the clamping groove.

[0007] When the sleeve is installed, the positioning boss is clamped by the clamping groove, and the positioning spring is embedded in the positioning groove to fix the upper and lower pressure plate assemblies.

[0008] By adopting the above technical solution, the prior art realizes clamping assembly by directly pressing the outer sleeve over the boss by friction, which is prone to produce debris and slight looseness. The improved assembly structure of the utility model eliminates the friction clamping, and the assembly is easy without producing debris.

[0009] Furthermore, the end surface of the positioning boss that meets the slot of the utility model is a rounded structure, so that the sleeve has a certain guiding effect when it is inserted, and the assembly is smoother.

[0010] Furthermore, a first epitaxial groove is provided on the right side of the positioning groove of the utility model, and a second epitaxial groove corresponding to the first epitaxial groove is provided on the right side of the positioning spring piece on the sleeve.

[0011] By adopting the above technical solution, although the device is for one-time use, in order to facilitate the possibility of disassembly and reinstallation of the device during the debugging and assembly stage, an epitaxial groove is reserved to facilitate prying with tools.

[0012] Furthermore, the upper and lower pressing plate assemblies described in the utility model include an upper pressing plate and a lower pressing plate, and positioning bosses are provided on the upper pressing plate and the lower pressing plate.

[0013] Furthermore, the upper pressing plate and the lower pressing plate described in the utility model are both provided with positioning grooves.

[0014] A reasonable number and reasonable position of bosses and positioning grooves can be set as needed, and the slots and positioning springs on the sleeve correspond accordingly to achieve a better fastening effect.

[0015] The beneficial effects of the utility model are as follows: the laparoscope assembly sleeve fixing structure of the utility model overcomes the shortcomings of the traditional technology and has the following advantages:

[0016] 1. High assembly efficiency and reduced labor intensity; 2. Eliminates the generation of debris due to friction between parts during assembly; 3. Also serves to fix the upper and lower pressure plates. BRIEF DESCRIPTION OF THE DRAWINGS
