DETAILED DESCRIPTION

[0032] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-8The present invention provides a technical solution: a portable cutting stapler with one-hand resetting, comprising a gun body 1, the gun body 1 is used to operate the stapler and control its various actions, the rotating part 2 of this case is installed on the gun body 1, and is used to operate the rotation of the stapler when both left and right hands can hold it with one hand, the connecting part 3 of this case is installed on the rotating part 2, and is used to connect the gun body 1 and a disposable stapler of matching model, the locking part 4 of this case is installed on the gun body 1, and is used to lock the angle of the stapler when both left and right hands can hold it with one hand, and the operating part 5 of this case is installed on the connecting part 3, and is used to perform cutting and stapler surgery on the patient's organ.

[0034] In the present invention, in order to distinguish the traditional technology that requires both hands to operate the stapler's stapler rotation, the present case adopts a more convenient single-handed operation, wherein the rotating part 2 includes a rotating device 21, the rotating device 21 is installed at the end of the gun body 1, and an angle control handle 22 is arranged on the rotating device 21. The rotating device 21 and the angle control handle 22 are both one of the components of the prior art product GCJQW-45M domestic intracavitary cutting stapler, and their function is to prompt the rotating device 21 to control the rotation of the stapler through the rotation of the angle control handle 22. The prior art is relatively mature, so this case will not be described in detail. In addition, the rotating part 2 also includes a rotating rod 23, and the top end of the rotating rod 23 and the handle shaft of the angle control handle 22 are fixedly sleeved with a gear 24, and a handle seat is also arranged between the angle control handle 22 and the rotating device 21, and the handle seat is fixed to the top of the outer wall of the rotating device 21. The angle control handle 22 The handle shaft passes through the handle base and is connected to the rotating device 21, and a toothed belt 25 is transmitted and meshed between two gears 24. The gear 24 on the handle shaft is located inside the handle base. A groove is provided at the end of the gun body 1. The design of the groove will not increase the original volume of the gun body 1, but adopts a certain cutting structure to fully improve the structural utilization rate under the volume of the original technical product. A rotating shaft 26 is rotatably connected to the inner wall of the groove. The bottom ends of the rotating shaft 26 and the rotating rod 23 are fixedly sleeved with a gear 27, and a toothed belt 28 is transmitted and meshed between the two gears 27. An angle control wheel 29 is fixedly sleeved at the bottom end of the rotating shaft 26. Under the connection of the toothed belt 25 and the toothed belt 28, the rotation of the angle control handle 22 can be controlled by the angle control wheel 29, and the angle control handle 22, which was originally operated from the top of the gun body 1 in the traditional technology, is changed to be controlled from the bottom of the gun body 1 near the handle.

[0035] In order to further improve the protection capability of the rotating part 2, the connecting part 3 of the present case includes an instrument rod 31, which is fixedly connected to the rotating device 21. The instrument rod 31 is also one of the components of the above-mentioned GCJQW-45M domestic intracavitary cutting stapler. Its function is to connect the nail magazine and the gun body 1. A protective cover 32 is installed on the outer wall of the instrument rod 31. The protective cover 32 can prevent the gear 1 24 and the gear 2 27 from being exposed to the outside, avoid surgical interference and also play a protective role. The top of the outer wall of the protective cover 32 is installed A micro screen 33 is installed, which adopts the UPS-lkg micro LCD screen of Shenzhen Hongruibo Electronics Co., Ltd., and is used to project the real-time images of the patient's organs during surgery onto the micro screen 33. The middle part of the rotating rod 23 passes through the instrument rod 31 and is rotatably connected to the instrument rod 31. The rotating rod 23 and the gear 1 24 and gear 2 27 connected to itself are all located in the protective cover 32. The protective cover 32 is set with an opening on one side close to the rotating device 21. The opening is to ensure that the normal transmission of the toothed belt 1 25 and the toothed belt 2 28 is not disturbed.

[0036] In this embodiment, in order to be able to lock the rotation angle with one hand when rotating the nail magazine with one hand, the locking part 4 of this case includes a sliding hole 41, which is opened on the gun body 1 and aligned with the groove. A magnet 42 is embedded on the top of the inner wall of the sliding hole 41, and a limiting hole 43 is opened on the bottom of the inner wall of the sliding hole 41. The limiting hole 43 passes through the top of the inner wall of the groove. The inner wall of the sliding hole 41 is slidably connected to a slider 44, and the bottom of the slider 44 is fixedly connected to a locking arm 45. The lock The stop arm 45 is slidably connected to the inner wall of the limiting hole 43, and levers 46 are fixedly connected to both sides of the slider 44. The slider 44 and the magnet 42 are attracted to each other by opposite charges. The ends of the two levers 46 extend to the outside of the sliding hole 41, and the bottom end of the locking arm 45 extends downward. The extended end of the locking arm 45 is engaged with the meshing teeth of the gear 2 27 on the rotating shaft 26. The engaging position is on the side of the gear 2 27 away from the meshing position of the toothed belt 2 28, and can directly lock the gear 2 27.

[0037] It is worth noting that in order to facilitate the detachable installation between the nail magazine and the stapler gun body 1, the operating part 5 in this case includes a mounting arm 51, one end of which is installed with a nail magazine assembly 52, and the other end of the mounting arm 51 is installed with a mounting plug 53, the nail magazine assembly 52 includes a nail magazine body and a left and right swing head, the nail magazine body is rotatably connected to the end of the mounting arm 51 through the left and right swing head, and the mounting arm 51 is clamped on the end of the instrument rod 31 away from the rotating device 21 through the mounting plug 53.

[0038] It is worth mentioning that an adjustment groove is provided on the handle of the gun body 1, and a firing device 6 is installed on the inner wall of the adjustment groove. Cutting scale grooves are provided on both sides of the outer wall of the gun body 1, and a scale sliding handle 7 is slidably connected to the inner wall of the cutting scale groove. The scale sliding handle 7 is also slidably connected to the outer wall of the gun body 1, and push arms 8 are fixedly connected on both sides of the bottom of the scale sliding handle 7. In order to enable the technician to assist in pushing the scale sliding handle 7 for cutting and returning to its original position with one hand, the two push arms 8 in this case extend to the root of the handle of the gun body 1.

[0039] Working principle: the surgeon can use his left or right hand to operate the stapler in this case independently, and connect and fix it with the instrument rod 31 through the installation plug 53 of the installation arm 51. The surgical part 5 in this case is a disposable product. The reason is that the stapler assembly 52 will be contaminated with bacteria when entering the patient's body, and it cannot be repeatedly used in different patients. In this case, the surgical part 5 and the connecting part 3 are detachable and installed, which can ensure that only the installation arm 51 of the surgical part 5 enters the patient's body, and the position of the instrument rod 31 does not enter the patient's body, which is more conducive to disinfection, cleaning and repeated use, thereby saving use costs, reducing surgical costs and benefiting the general public. The surgeon holds the gun body 1 The index finger of the user can be used to turn the angle control wheel 29, causing the rotating shaft 26 to drive the gear 2 27 to rotate, thereby utilizing the toothed belt 28 to drive the rotating rod 23 to rotate, and then the toothed belt 1 25 on the gear 1 24 to drive the handle shaft to rotate, so as to achieve the goal of freely manipulating the angle control handle 22 above the gun body 1 with the index finger of one hand, thereby achieving the state of one-handed grip while still being able to operate the rotation angle of the nail magazine assembly 52 with one hand, which on the one hand improves the convenience of operation, and on the other hand avoids the problem of the nail magazine assembly 52 shaking and pulling in the patient's body due to poor force control to maintain balance during two-hand operation, thereby reducing the risk of organ damage during surgery and improving the safety of surgery.

[0040] After the angle of the nail magazine assembly 52 is adjusted, the index finger can be used to quickly push the lever 46 from top to bottom, so that the slider 44 is separated from the adsorption of the magnet 42 and slides down to drive the locking arm 45 to extend to the groove. The locking arm 45 is directly inserted into the meshing teeth of the gear 2 27 on the rotating shaft 26 in a triangular shape to achieve the effect of limited locking. The gear 2 27 that is limited and locked cannot cause rotation, thereby achieving the purpose of quickly fixing the rotation angle of the nail magazine assembly 52. ​​Conversely, pushing the lever 46 from bottom to top with the index finger will cause the locking arm 45 to disengage from the meshing teeth of the gear 2 27, thereby adsorbing the slider 44 through the suction force of the magnet 42, preventing the slider 44 from slipping and then releasing the lock, and restoring the free rotation of the nail magazine assembly 52.

[0041] The trigger 6 is used to control the loading and matching of the staples in the staple magazine assembly 52, and to control the cutting progress of the cutting knife. By cooperating with the scale slide handle 7, the current cutting knife advance distance can be accurately fed back from the cutting scale groove, which is beneficial to the safe implementation of the operation. The surgeon's thumb operates the push arm 8 to drive the scale slide handle 7 to advance or return, and human compensation operation is performed when the cutting knife encounters obstruction, which is more conducive to the safety and controllability of the cutting knife's advance and retraction.

[0042] In this case, the cutting stapler is operated with one hand. Both the left and right hands can freely operate the rotation, locking and cutting advance and retraction of the stapler assembly 52 through the index finger and thumb, making the operation process more efficient and convenient. The micro screen 33 can be used to observe the surgical status of the patient's internal organs from the gun holding position in real time. The surgeon does not need to repeatedly shake his head to observe the surgical display screen, which is more intuitive and convenient. In the existing GCJQW-45M domestic intracavitary cutting stapler, the control module and electric energy-driven control method used to realize stapler control and cutting control are already very common and mature technologies in this field, so this case will not be elaborated in detail.
