Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to an electric circumcision stapler with a pressure-holding function. Background Technology

[0002] Clinical circumcision and suturing is a surgical procedure involving the cutting and suturing of the foreskin tissue of the male penis. A circumcision stapler is one of the most commonly used surgical instruments in this procedure. The working principle of the circumcision stapler is similar to that of a stapler. The foreskin tissue is placed and fixed between the glans and the staple cartridge assembly. The tissue is compressed appropriately by adjusting the distance between the staple cartridge assembly and the glans. When the distance between the staple cartridge assembly and the glans reaches a safe range for effective suturing, the stapler is fired. Upon firing, the circular blade is pushed out to cut the tissue, while the staples in the cartridge are compressed into a predetermined shape, completing the cutting and suturing process.

[0003] Traditional circumcision staplers are fired mechanically, requiring the surgeon to manually apply considerable force during the procedure. Since each surgeon's habits and experience differ, the amount of force applied can vary, leading to significant surgical errors and compromising surgical stability. Furthermore, to ensure effective hemostasis and staple stability, the surgeon holds the stapler firmly for a period after anastomosis, maintaining pressure throughout the process, which can easily cause hand fatigue.

[0004] Traditional mechanical circumcision staplers rely on the surgeon's experience to determine the success of the procedure, making it difficult to guarantee surgical stability. The force, speed, and duration of pressure applied during use all affect the effective cutting of tissue and hemostasis. Summary of the Invention

[0005] This invention is an electric circumcision stapler with a pressure-holding function, which achieves stable anastomosis and continuous pressure holding.

[0006] This invention is achieved through the following technical solution: an electric circumcision stapler with a pressure-holding function, the main body of which is a circumcision stapler.

[0007] The circumcision stapler mainly includes a housing, a glans cover 1, a pusher plate 2, a straight pusher tube 3, an adjusting nut 7, and a screw assembly 8;

[0008] The pusher plate 2 is located at the front end of the housing, and the straight push tube 3 is slidably installed inside the housing, with the front end of the housing connected to the pusher plate 2;

[0009] The lead screw assembly 8 is rotatably mounted on the rear end of the housing, and the adjusting nut 7 is fixed to the tail end of the lead screw assembly 8 so as to drive the lead screw assembly 8 to rotate and move back and forth at the same time.

[0010] The glans cap 1 is located at the front end of the push plate 2 and passes through the push plate 2 and the straight push tube 3 and is connected with the screw rod set 8, so that the adjusting nut 7 drives the glans cap 1 to move forward and backward;

[0011] It also includes a firing handle, a linkage, a motor, a first motor control unit, a second motor control unit and a rotation control unit;

[0012] The firing handle is pivoted to the firing handle and connected with the motor to control the start of the motor;

[0013] The linkage is installed in the housing and connected with the straight push tube 3 to drive the straight push tube 3 to move forward and backward;

[0014] The first motor control unit is installed in the housing, connected with the motor and controls the motor to stop rotating when firing;

[0015] The second motor control unit is installed in the housing, connected with the motor and controls the motor to stop rotating when firing;

[0016] The rotation control unit is installed in the motor, and the movement of the linkage is driven by the rotation of the rotation control unit and the firing of the first motor control unit and the second motor control unit is controlled;

[0017] The position relationship of the rotation control unit, the linkage, the first motor control unit and the second motor control unit satisfies that when the firing handle activates the motor and drives the rotation control unit to rotate by an angle a, the linkage drives the push plate 2 to push forward to the most front end, and at the same time the first motor control unit is excited by the rotation control unit to make the motor stop rotating;

[0018] When the firing handle activates the motor and drives the rotation control unit to rotate by an angle b again, the linkage drives the push plate 2 to reset, and at the same time the second motor control unit is excited by the rotation control unit to make the motor stop rotating.

[0019] Compared with the prior art, the beneficial effects of the present application are:

[0020] 1、The present application realizes firing by motor driving, the anastomosis process is continuous and smooth, the firing force is uniform and stable; and the function of continuous pressure maintaining is set, which reduces the operation burden of the doctor.

[0021] 2、Compared with the traditional mechanical prepuce anastomat, after realizing one-time cutting and suturing, the handle can still be pressed to realize secondary cutting, which may cause harm to the patient. The electric prepuce anastomat is disposable, and the internal structure is arranged so that it can only realize one-time cutting and suturing.

[0022] 3. The operator only needs to press the firing handle slightly to realize the firing when firing the present application, without pressing the instrument handle to realize the firing with great force like the traditional prepuce anastomat, so that the hand fatigue of the doctor can be avoided.

DETAILED DESCRIPTION

[0028] In the description of the present application, it should be understood that the terms "front", "back", etc. indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0029] The present application will be described in detail below in conjunction with the drawings:

[0030] As shown in Figure 1 , 2 : an electric prepuce cutting anastomat with pressure maintaining function, the main body of which is a prepuce cutting anastomat,

[0031] The prepuce cutting anastomat mainly comprises a shell, a glans cap 1, a push pin plate 2, a straight push tube 3, an adjusting nut 7, and a screw rod set 8.

[0032] The push pin plate 2 is located at the front end of the shell, and the straight push tube 3 is installed in the shell to slide back and forth, and the front end of the shell is connected to the push pin plate 2.

[0033] The screw rod set 8 is rotationally installed at the rear end of the shell, and the adjusting nut 7 is fixed at the tail end of the screw rod set 8 to drive the screw rod set 8 to rotate and move back and forth at the same time.

[0034] The glans cap 1 is located at the front end of the push plate 2 and passes through the push plate 2 and the straight push tube 3 and is connected with the screw rod set 8 to realize the forward and backward movement of the adjusting nut 7;

[0035] It also includes a firing handle, a linkage, a motor, a first motor control unit, a second motor control unit, and a rotation control unit;

[0036] The firing handle is pivoted to the firing handle and connected with the motor to control the start of the motor;

[0037] The linkage is installed in the housing and connected with the straight push tube 3 to drive the straight push tube 3 to move forward and backward;

[0038] The first motor control unit is installed in the housing, connected with the motor, and controls the motor to stop rotating when firing;

[0039] The second motor control unit is installed in the housing, connected with the motor, and controls the motor to stop rotating when firing;

[0040] The rotation control unit is installed in the motor, and the movement of the linkage is driven by the rotation of the rotation control unit, and the firing of the first motor control unit and the second motor control unit is controlled;

[0041] The position relationship of the rotation control unit, the linkage, the first motor control unit, and the second motor control unit satisfies that when the firing handle activates the motor and drives the rotation control unit to rotate by an angle a, the linkage drives the push plate 2 to move forward to the most forward end, and at the same time, the first motor control unit is excited by the rotation control unit to make the motor stop rotating;

[0042] When the firing handle activates the motor and drives the rotation control unit to rotate by an angle b again, the linkage drives the push plate 2 to reset, and at the same time, the second motor control unit is excited by the rotation control unit to make the motor stop rotating.

[0043] Here, when the firing handle activates the motor and drives the rotation control unit to rotate by an angle a, the push plate 2 is already pushed forward; and when the rotation control unit completes the rotation by an angle a, the push plate 2 is also pushed forward to the most forward end, at this time, the first motor control unit is excited by the rotation control unit to control the motor to stop rotating, and the push plate 2 can stay at the most forward end to complete the pressure maintaining process.

[0044] When the firing handle is pressed again, the motor rotates again, at this time, the motor drives the rotation control unit to rotate by an angle b; when the rotation control unit starts to rotate, it will release the control of the linkage, and the linkage will drive the push plate 2 to return to the initial position; at the same time, the rotation control unit rotating by an angle b will excite the second motor control unit to control the motor to stop rotating. The motor stops rotating this time is irreversible, that is, when the firing handle is pressed again, the motor will not start again.

[0045] As shown in Figures 3-4 : the rotation control unit is a rotating wheel 12 with three protrusions, wherein the switch protrusion 51 is used to trigger the first motor control unit and the second motor control unit, the forward dialing protrusion 53 is used to dial the linkage and drive the push pin plate 2 forward, and the reverse dialing protrusion 52 is used to dial the linkage and drive the push pin plate 2 backward.

[0046] By setting three different protrusions, the rotating wheel 12 can activate different functional modules at different stages during rotation according to requirements.

[0047] The linkage includes a swing arm 5 and a push piece 4, the front end of the push piece 4 is connected to the tail of the straight push tube 3, and the rear end of the push piece 4 is hinged to the passive end of the swing arm 5.

[0048] The middle part of the swing arm 5 is provided with a limiting hole, and the limiting hole is sleeved on the limiting shaft arranged in the shell; the reset structure is a torsion spring arranged between the swing arm 5 and the limiting shaft.

[0049] The initial position of the driving end of the swing arm 5 is located on the trajectory passed by the forward dialing protrusion 53.

[0050] The final position of the driving end of the swing arm 5 is located on the trajectory passed by the reverse dialing protrusion 52.

[0051] The swing arm 5 here is equivalent to a seesaw, when the driving end of the swing arm 5 is pushed by the forward dialing protrusion 53, the passive end of the swing arm 5 drives the push piece 4 to move forward. Conversely, when the driving end of the swing arm 5 is pushed by the reverse dialing protrusion 52, the passive end of the swing arm 5 drives the push piece 4 to move backward.

[0052] The first motor control unit includes a trigger pole 15 and a pressure maintaining pole 16, both of which are installed in the shell, and the trigger pole 15 and the pressure maintaining pole 16 are electrically connected with the motor 11; so that when the trigger pole 15 and the pressure maintaining pole 16 are in contact, the motor 11 stops rotating;

[0053] Among them, the installation position of the trigger pole 15 is located on the trajectory of the switch protrusion 51.

[0054] When the rotating wheel 12 rotates, the switch protrusion 51 also rotates and pushes the trigger pole 15 and the pressure maintaining pole 16 into contact, so that the motor stops rotating, and at this time the trigger pole 15 and the pressure maintaining pole 16 are in continuous contact.

[0055] The second motor control unit includes a stopper 11 and an electronic switch 9; both of which are installed in the shell, and the electronic switch 9 is electrically connected with the motor 11; so that when the electronic switch 9 is triggered by the dialing stopper 11, the motor 11 stops rotating;

[0056] The installation position of the stop sheet 11 is located on the track of the switch protrusion 51.

[0057] When the rotating wheel 12 rotates, the switch protrusion 51 rotates and finally pushes the stop sheet 11, so that the stop sheet 11 closes the electronic switch, and the motor is no longer started.

[0058] The switch protrusion 51, the forward pushing protrusion 53 and the reverse pushing protrusion 52 are distributed in the axial direction of the rotating shaft of the rotating wheel 12. Since the forward pushing protrusion 53 needs to drive the continuous movement of the swing arm 5, it occupies a large area. In order to facilitate the position distribution of the three protrusions, the three protrusions are distributed in the axial direction of the rotating shaft of the rotating wheel 12.

[0059] The forward pushing protrusion 53 is a semicircular protrusion with increasing radius. The distance from the outer side of the forward pushing protrusion 53 to the axis of the rotating wheel 12 increases in the clockwise direction of the rotating wheel 12. Since the radius gradually changes, the swing arm 5 will gradually rotate in one direction from the beginning to the end of the contact between the forward pushing protrusion 53 and the swing arm 5, so as to realize the forward movement of the straight pushing tube.

[0060] The reverse pushing protrusion 52 is an arc-shaped protrusion. The distance from the inner side of the reverse pushing protrusion 52 to the axis of the rotating wheel 12 decreases in the clockwise direction of the rotating wheel 12. A convex point 54 is arranged on the driving end of the swing arm 5 and is in contact with the reverse pushing protrusion 52.

[0061] Since the swing arm 5 is pushed away by the forward pushing protrusion 53, in order to ensure the reset of the swing arm 5, the reverse pushing protrusion 52 with a gradually changing arc is added. The gradually changing arc of the reverse pushing protrusion 52 is located on the inner side, and the convex point 54 is arranged on the driving end of the swing arm 5 and is in contact with the reverse pushing protrusion 52. When the rotating wheel 12 rotates, the reverse pushing protrusion 52 can contact the convex point 54 and guide the swing arm 5 to reset, so as to realize the backward movement of the straight pushing tube.

[0062] It also comprises a battery slot, and a battery 6 is arranged in the battery slot and is electrically connected with the motor 11.

[0063] It also comprises a safety button 13, which is installed on the shell and located behind the firing handle 14.

[0064] In addition, it should be noted that the reset of the swing arm 5 can also be achieved by the following method:

[0065] That is, the rotating control unit is a rotating wheel 12 with three protrusions. The switch protrusion 51 is used to trigger the first motor control unit and the second motor control unit. The forward pushing protrusion 53 is used to push the linkage and drive the forward movement of the push pin plate 2. The linkage is provided with a reset structure for controlling the linkage and driving the backward movement of the push pin plate 2.

[0066] Specifically, the linkage comprises the swing arm 5 and the push piece 4, the front end of the push piece 4 is connected to the tail of the straight push tube 3, and the rear end of the push piece 4 is hingedly connected to the passive end of the swing arm 5;

[0067] The middle part of the swing arm 5 is provided with a limiting hole, and the limiting hole is sleeved on a limiting shaft arranged in the shell; the reset structure is a torsion spring arranged between the swing arm 5 and the limiting shaft;

[0068] The initial position of the swing arm 5 is located on a trajectory through which the positive driving protruding block 53 passes.

[0069] It should be noted that if the torsion spring is not arranged here, or a spring is sleeved on the outer periphery of the straight push tube, and the two ends of the spring are connected to the shell and the straight push tube respectively, the spring applies an external force in the backward direction to the straight push tube.

[0070] The use method of the application is as follows:

[0071] S1. When used, the tissue is fixed on the glans cap 1, and then the glans cap 1 is inserted into the screw rod set 8; the rotary adjusting nut 7 can drive the screw rod set 8 to make reciprocating motion in the linear direction, so as to drive the glans cap 8 to move forward and backward.

[0072] S2. The rotary adjusting nut 8 is rotated to retract the glans cap 1, so that the tissue is compressed to reach the safe range of effective suturing.

[0073] S3. The battery 6 is inserted, and the safety button 13 is opened.

[0074] S4. The trigger handle 14 is pressed once to trigger the rotation of the motor 10; the motor 10 drives the rotating wheel 12 to rotate; the positive driving protruding block 53 of the rotating wheel 12 pushes the swing arm 5; the swing arm 5 drives the push piece 4, the straight push rod 3 and the push nail plate 2 in sequence; the push nail plate 2 is pushed out to realize the cutting and suturing of the tissue.

[0075] S5. While the push nail plate 2 is pushed out to realize the cutting and suturing, the rotating wheel 12 pushes the trigger pole 15 to deform, so that the trigger pole 15 is in contact with the pressure maintaining pole 16 to realize conduction, so that the motor 10 stops rotating to realize pressure maintaining.

[0076] S6. The motor 10 stops rotating to enter the pressure maintaining state, and the pressure maintaining time is determined by the doctor.

[0077] S7. The trigger handle 14 is pressed again, the motor 10 continues to rotate, and the reverse driving protruding block 52 on the rotating wheel 12 hooks the swing arm 5 back, and the push nail plate 2 returns to the initial state.

[0078] S8. When the push nail plate 2 is retracted to the end, the rotating rotating wheel 12 starts to press the stop piece 11 to make it press the electronic switch 9 to cut off the power supply, and always maintains the power-off state; the trigger handle 14 cannot realize the rotation of the motor 10 again.

[0079] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
