Technical Field

[0001] The present invention belongs to the technical field of staplers, and particularly relates to an electric endoscopic cutting stapler. Background Art

[0002] A stapler, as can be found from existing materials or entries, is a device used in medicine to replace manual suturing. Its main working principle is to use titanium staples to sever or anastomose tissues, similar to a stapler. According to different application scopes, it can be mainly divided into skin staplers, circular staplers for the digestive tract (esophagus, gastrointestinal tract, etc.), rectal staplers, circular hemorrhoid staplers, circumcision staplers, vascular staplers, hernia staplers, lung cutting and suturing devices, etc. Moreover, due to the development of modern technology and the improvement of manufacturing techniques, the staplers used clinically are of reliable quality, convenient to use, tight and of appropriate tightness. Especially, the advantages of rapid suturing, simple operation, few side effects and surgical complications have enabled tumor surgeries that could not be resected in the past to remove the lesions.

[0003] Currently, the operation method of a stapler generally requires holding a single - hand operation handle and then performing the operation. For existing staplers of the same type, the size of the grip in the handle is the same. For staplers of different models, the differences lie in the anastomosis length, staple height or the number of staples, etc. The size of the grip in their handles is basically the same. However, due to different hand sizes of different users, the degree of fit of holding the stapler handle is different, which will affect the strength of different people holding the stapler, and further affect the stability and accuracy of the cutting and anastomosis operation when holding the stapler. Especially for users who are new to using staplers, this problem is particularly prominent, which is also the most frequently reported problem found by our company during the investigation of the use results of staplers. Summary of the Invention

[0004] The purpose of the present invention is to provide an electric endoscopic cutting stapler, aiming to solve the problem in the prior art that due to different hand sizes of different users, the degree of fit of holding the stapler handle is different, which will affect the strength of different people holding the stapler, and further affect the stability and accuracy of the cutting and anastomosis operation when holding the stapler.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an electric endoscopic cutting stapler, including a stapler body. The grip of the handle in the stapler body includes an inner grip and an outer grip. The inner grip is integrally manufactured with the stapler body, and the number of the outer grips is more than one;

[0006] The outer grip and the inner grip are of a hollow structure. The outer grip is sleeved on the inner grip. The inner diameters of different outer grips sleeved on the inner grip are the same, and the outer diameters of different outer grips are different.

[0007] An arc-shaped groove is formed on the outer surface of the inner grip, and an electromagnetic block is fixed in the arc-shaped groove. The electromagnetic block is powered by a battery pack in the stapler body.

[0008] An arc-shaped groove identical to the outer surface of the inner grip is formed on the inner surface of the outer grip. A magnetic block is fixed in the arc-shaped groove of the outer grip. After the electromagnetic block is powered on, it adsorbs to the magnetic block. After the inner grip and the outer grip are sleeved, the electromagnetic block and the magnetic block come into contact.

[0009] Preferably, a heat-conducting strip is provided in the inner wall of the outer grip. The heat-conducting strip penetrates through the magnetic block and then contacts the electromagnetic block.

[0010] Preferably, the heat-conducting strip is made of copper.

[0011] Preferably, a positioning hole is formed at the bottom of the outside of the inner grip, and a positioning post is provided at the bottom of the inside of the outer grip. The positioning post and the positioning hole are matched with each other.

[0012] Preferably, the positioning post is of a hollow structure.

[0013] Preferably, an anti-slip rubber sleeve is sleeved on the surface of the outer grip.

[0014] Preferably, anti-slip patterns are provided on the surface of the anti-slip rubber sleeve.

[0015] Preferably, the battery pack in the stapler body is externally connected with a wire, and the battery pack is electrically connected to the external wire.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figures 1-5 As shown, in order to improve the stability and accuracy of holding the stapler for cutting and stapling operations, the present invention proposes an electric laparoscopic cutting stapler to solve the above problems, as follows:

[0028] The electric laparoscopic cutting stapler includes a stapler body 1. The structure, working principle, usage method, etc. of this stapler are exactly the same as those of the staplers already disclosed in the prior art. Those skilled in the art can fully understand the usage method of the stapler body 1 through querying or understanding the known technology. Therefore, in the present invention, the specific structure, working principle, usage method, etc. of the stapler body 1 will not be described in detail. The key innovation of the present invention lies in the grip of the handle 11 in the stapler body 1, specifically as follows:

[0029] The grip of the handle 11 includes an inner grip 2 and an outer grip 21. Among them, the inner grip 2 is integrally manufactured with the stapler body 1. The number of outer grips 21 is more than one. The outer grip 21 and the inner grip 2 are hollow structures. A motor for driving the stapler body 1 to work is placed inside the inner grip 2. The outer grip 21 is sleeved on the inner grip 2. An arc-shaped groove is formed on the outer surface of the inner grip 2, and an electromagnetic block 22 is fixed in the arc-shaped groove. Moreover, the inner diameters of different outer grips 21 sleeved on the inner grip 2 are the same, and the outer diameters of different outer grips 21 are different. The electromagnetic block 22 is powered by a battery pack 15 in the stapler body 1. Correspondingly, an arc-shaped groove identical to the outer surface of the inner grip 2 is formed on the inner surface of the outer grip 21, and a magnetic block 23 is fixed in the arc-shaped groove of the outer grip 21. After the electromagnetic block 22 is powered on, it adsorbs the magnetic block 23. After the inner grip 2 and the outer grip 21 are sleeved, the electromagnetic block 22 and the magnetic block 23 come into contact;

[0030] When it is necessary to use the stapler body 1 for cutting and stapling operations, first, the user can select an outer grip 21 with a different outer diameter according to the size of their hand shape. After selecting an outer grip 21 with a suitable outer diameter, sleeve it on the inner grip 2. At this time, the electromagnetic block 22 and the magnetic block 23 come into contact. Then, before using the stapler for relevant operations, the battery pack 15 in the stapler body 1 starts to supply power, and then supplies power to the electromagnet, so that the electromagnetic block 22 adsorbs the magnetic block 23, thereby realizing the fixation of the outer grip 21 and the inner grip 2. When the relevant operations are completed, the battery pack 15 is powered off. At this time, the outer grip 21 can be pulled out from the inner grip 2;

[0031] Therefore, for the electric laparoscopic cutting stapler designed in the present invention, when in use, an outer grip 21 with a different outer diameter and matching the hand shape can be selected according to the size of the user's hand shape, which helps the user better hold the stapler body 1 for cutting and stapling operations, improves the stability and accuracy of the user holding the stapler body 1 for cutting and stapling operations, and is especially suitable for beginners, such as students in medical schools, etc., who can quickly master the usage method, usage skills, and usage strength of the stapler body 1, so that the present invention is applicable to relevant experimental operations for learning to operate the stapler;

[0032] Moreover, the outer handle 21 and the inner handle 2 are fixed by the design of the electromagnetic block 22 and the magnetic block 23. Compared with the use of a snap-on or threaded connection, the advantage is that the outer handle 21 and the inner handle 2 can be quickly disassembled, that is, after the previous user has finished using it and the stapler body 1 has been used and the power is cut off, the outer handle 21 can be pulled out from the inner handle 2 without any other unnecessary operations. The next user can select an outer handle 21 that matches the hand shape, put it on the inner handle 2, and continue to carry out related experiments such as stapler learning operation, thereby improving the efficiency of the stapler learning operation experiment.

[0033] It should be noted that the size of the inner diameter of the outer grip 21 can be reasonably set according to the size of the inner grip 2 of the stapler body 1 of different models, but the premise is that after the outer grip 21 is sleeved on the inner grip 2, it does not affect the normal use of the closing trigger 12, the safety button 13 and the firing button 14 on the stapler body 1. Therefore, in actual production and manufacturing, the outer grip 21 matching the size of the inner grip 2 in the stapler body 1 of different models can be produced. At the same time, the shapes of the inner grip 2 and the outer grip 21 produced by different manufacturers may be different. The appendix of the present invention Figures 2-5 The shapes of the conventional inner handle 2 and outer handle 21 are shown in the figure to facilitate the understanding of those skilled in the art. However, in actual production, the shapes of the inner handle 2 and outer handle 21 can also be changed, which does not affect the functions of the inner handle 2 and outer handle 21.

[0034] Furthermore, a heat conducting strip 3 is provided in the inner wall of the outer handle 21, and the heat conducting strip 3 passes through the magnetic block 23 and contacts the electromagnetic block 22. The material of the heat conducting strip 3 is copper. Such a design, on the one hand, because the electromagnetic block 22 will generate heat when energized, and part of its heat will be conducted away through the heat conducting strip 3, it can prevent the heat of the electromagnetic block 22 from being concentrated and demagnetization from occurring during long-term and multiple user-performed experimental operations such as cutting and anastomosis, thereby affecting the firmness of the outer handle 21 and the inner handle 2 during use. At the same time, after the heat of the electromagnetic block 22 is conducted away, it is transferred to the outer handle 21, which can improve the comfort of holding the stapler body 1, and is suitable for performing related experimental operations such as cutting and anastomosis in winter when the temperature is lower, so that the user is in a more relaxed and comfortable state when holding the outer handle 21, thereby improving the stability of the user when using the stapler body 1 for operation.

[0035] In other embodiments of the present invention, a positioning hole 4 is provided at the bottom outside the inner grip 2, and a positioning post 5 is provided at the bottom inside the outer grip 21. The positioning post 5 and the positioning hole 4 are mutually matched. The functions of the positioning hole 4 and the positioning post 5 are that when the inner grip 2 and the outer grip 21 are sleeved, the positioning post 5 in the outer grip 21 can be inserted into the positioning hole 4 of the inner grip 2, which is convenient for the quick sleeving of the inner grip 2 and the outer grip 21. At the same time, when the electromagnetic block 22 is not powered on, the inner grip 2 and the outer grip 21 are preliminarily fixed to prevent the inner grip 2 and the outer grip 21 from separating when the electromagnet in the stapler body 1 is not powered on or powered off after use after the inner grip 2 and the outer grip 21 are sleeved.

[0036] In some embodiments, the positioning post 5 is of a hollow structure. When the hollow-structured positioning post 5 is inserted into the positioning hole 4, it communicates with the hollow structure of the inner grip 2, so that external air can enter the hollow structure of the inner grip 2 to dissipate heat from the motor in the inner grip 2 and the electromagnetic block 22 on the inner wall of the inner grip 2, preventing the motor and the electromagnetic block 22 inside from overheating and affecting the use of the stapler body 1. Thus, when a beginner uses the stapler body 1 to perform related experimental operations such as cutting and stapling, a longer usage time can be obtained.

[0037] In some embodiments, a non-slip rubber sleeve 6 is sleeved on the surface of the outer grip 21, which can improve the stability of the use of the stapler body 1. At the same time, in order to further improve the stability of the use of the stapler body 1, anti-slip patterns are provided on the surface of the non-slip rubber sleeve 6. Specifically, the non-slip rubber sleeve 6 can be sleeved on the surface of the outer grip 21 by virtue of its own ductility.

[0038] In some embodiments, a wire 7 is externally connected to the battery pack 15 in the stapler body 1, and the battery pack 15 is electrically connected to the external wire 7, so as to be powered by an external power source. In the prior art, the battery in the stapler is generally disposable, and the usual number of uses is about twelve times. However, when a beginner uses the stapler body 1 to perform related experimental operations, if a disposable battery is still used, it will cause waste of the battery. Therefore, by supplying power to the battery pack 15 in the stapler body 1 through an external power source, waste of the battery can be reduced. At the same time, the efficiency of the user using the stapler body 1 to perform related experimental operations such as cutting and stapling can also be improved, that is, after the previous beginner uses the stapler body 1 to perform related experimental operations such as cutting and stapling, the next beginner can continue to use the stapler body 1 to perform related experimental operations such as cutting and stapling without replacing the battery.

[0039] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
