Description

Technical Field

[0001] This utility model belongs to the field of anastomosis device technology, specifically relating to an anti-accidental contact anastomosis device. Background Technology

[0002] Anastomosing devices are medical devices used to replace traditional manual suturing. Their main function is to separate or anastomose tissues using titanium or stainless steel staples, thereby enabling the connection, repair, and reconstruction of organs.

[0003] In related technologies, anastomotic devices have widely adopted electric drive to achieve more precise operation. While operation is more convenient with electric assistance, because the handle and control trigger are positioned close together, if medical staff accidentally press the trigger during alignment near the wound, the trigger will react rapidly under electric assistance, causing the anastomosis position to be incorrect and resulting in unnecessary accidents.

[0004] Therefore, there is an urgent need to design a stapler that prevents accidental contact, in order to solve the technical problem that accidental contact with the stapler when it is applied to the wound can lead to incorrect anastomosis position.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This disclosure provides at least one embodiment of an anti-accidental contact stapler.

[0007] In a first aspect, embodiments of this disclosure provide an anti-accidental touch stapler, comprising: a stapler body having a handle;

[0008] The control trigger has one end hinged to the stapler body and the other end tilted toward one side of the handle.

[0009] A locking lever, one end of which is mounted on the handle, and the other end extends toward the control trigger;

[0010] The locking lever is L-shaped, with the end of the locking lever away from the handle abutting against the control trigger.

[0011] In one alternative embodiment, the locking lever includes a connecting section and a clamping section, one end of the connecting section being connected to a handle and the other end being hinged to the clamping section.

[0012] In one alternative implementation, the angle between the connecting section and the clamping section is an acute angle.

[0013] In one alternative embodiment, the handle has a top block, and a locking lever is hinged to the handle;

[0014] The top block corresponds to the locking lever.

[0015] In one alternative embodiment, the handle has a groove, and the top block is slidably disposed within the groove.

[0016] In one alternative embodiment, the outer side wall of the top block has anti-slip texture.

[0017] Secondly, this disclosure also provides an anti-accidental touch stapler, including: a stapler body having a handle;

[0018] The control trigger has one end hinged to the stapler body and the other end tilted toward one side of the handle.

[0019] The locking lever includes a connecting section and a clamping section. One end of the connecting section is connected to the handle, and the other end is hinged to the clamping section. The end of the clamping section away from the connecting section abuts against the control trigger.

[0020] The angle between the connecting section and the tightening section is an acute angle;

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described examples are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Research has found that staplers are now widely used with electric drive for more precise operation. While electric assistance makes operation more convenient, the handle and control trigger are positioned close together. If medical staff accidentally press the trigger during alignment near the wound, the trigger will react rapidly under electric assistance, causing the anastomosis position to be incorrect and resulting in unnecessary accidents.

[0037] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as the inventor's contribution to this disclosure.

[0038] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] Based on the above research, and referring to Figure 1 This disclosure provides an anti-accidental contact stapler, comprising: a stapler body 1 with a battery installed inside; a handle 2 at the tail end of the stapler, and a control trigger 3 on one side of the handle 2, the control trigger 3 being electrically connected to the battery; one end of the control trigger 3 is hinged to the stapler body 1, and the other end is tilted towards the handle 2; when the operator pulls the control trigger 3 towards the handle 2, the battery discharges and controls the stapler head to perform the stapler operation.

[0041] Reference Figure 1 In at least one embodiment, to prevent the operator from accidentally triggering the control trigger 3 while aligning the wound, thus causing the stapler to prematurely perform the wound closure operation without proper alignment, a locking lever 4 is provided between the handle 2 and the control trigger 3. One end of the locking lever 4 is mounted on the handle 2, and the other end extends towards the control trigger 3 and abuts against one side of the control trigger 3. The locking lever 4 is L-shaped and adaptable to bend.

[0042] Reference Figure 3 In at least one embodiment, the locking lever 4 is divided into two sections: a connecting section 41 and a tightening section 42. One end of the connecting section 41 is hinged to the handle 2, and the other end is hinged to the tightening section 42. This allows the locking lever 4 to form a flexible and rotatable rod. A torsion spring is provided at the hinge between the connecting section 41 and the tightening section 42 to keep the locking lever 4 in an L-shape under normal conditions. A torsion spring is also provided at the hinge between the connecting section 41 and the handle 2. The tightening section 42 can prevent the control trigger 3 from moving towards the handle 2, thereby limiting the travel of the control trigger 3 and preventing the movement of the control trigger 3 from triggering the anastomosis device. On the other hand, when the operator aligns the wound, they need to use one finger to rotate the connecting section 41 to unfold it into a straight shape, thereby releasing the obstruction effect on the control trigger 3.

[0043] Reference Figure 3 In at least one embodiment, the angle between the connecting section 41 and the clamping section 42 is an acute angle to ensure that the clamping section 42 is not flattened when the control trigger 3 presses against it.

[0044] Reference Figure 2In at least one embodiment, in order to press the connecting section 41 against the control trigger 3 to adjust its rotatable stroke, the handle 2 has a top block 21, and a locking lever 4 is hinged to the handle 2. The top block 21 corresponds to the locking lever 4. When the connecting section 41 rotates to abut against the top block 21, the connecting section 41 reaches its maximum stroke, and consequently, when the control trigger 3 rotates to engage with the connecting section 41, the control trigger 3 also reaches its maximum stroke.

[0045] Reference Figure 2 In at least one embodiment, the handle 2 has a groove 22, and the top block 21 is slidably disposed within the groove 22. By controlling the position of the top block 21 within the groove 22, the maximum rotation angle of the connecting section 41 can be controlled, thereby controlling the maximum rotation angle of the control trigger 3. Therefore, when the stapler is not in use, the operator can slide the top block 21 to the position in the groove 22 closest to the connecting section 41. At this time, the top block 21 abuts against the connecting section 41 to maintain the maximum opening angle, and the control trigger cannot be pressed. When the operator uses the stapler, the position of the top block 21 within the groove 22 can be adjusted according to the depth of the wound to ensure control of the degree of engagement of the trigger 3.

[0046] Reference Figure 2 In at least one embodiment, the outer side wall of the top block 21 has anti-slip texture 23 to facilitate the operator to control the position of the top block 21 in the groove 22.

The apparatus embodiments described above are merely illustrative. For example, the division of units is only a logical functional division, and in actual implementation, there may be other division methods. Furthermore, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Based on the above-described ideal embodiments of this utility model, and through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification; its technical scope must be determined by the scope of the claims.
