Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an electric circumcision stapler. Background Art

[0002] Clinical studies have found that in the male population, phimosis or prepuce is a common disease in the reproductive system. It is mainly manifested in that the foreskin covers the entire glans and the external opening of the urethra, and forms a semi-open cavity with the coronal sulcus. Prepuce or phimosis can easily cause urinary tract infection and lead to chronic prostatitis, which will cause a series of symptoms such as back pain, impotence and premature ejaculation. Therefore, removing the excessive foreskin is one of the best measures to prevent these diseases.

[0003] At present, circumcision is mainly used to treat phimosis or prepuce. Using a circumcision stapler to cut the excessive foreskin and staple the wound at the same time can greatly reduce the operation time and reduce the patient's pain. However, the commonly used circumcision stapler currently uses the medical staff's hand force to press the wrench to cut and staple. However, due to poor control of hand strength and different hand strengths of different medical staff, shaking is prone to occur during anastomosis. All of these will increase the risk of surgery and lead to problems such as uneven cutting, incomplete anastomosis, and bleeding.

[0004] In view of this, an electrically-driven circumcision stapler is very necessary, such as the built-in electric circumcision stapler with patent application number CN107041775A and the electric circumcision stapler and operating table with patent application number CN109009343A, both of which put forward the concept of electrically-driven circumcision stapler, but these two schemes are both holistic designs, in which the motor, control system, power transmission system, etc. cannot be reused, which leads to excessively high cost of the whole set, and also leads to excessively high cost of use for patients, increasing social burden.

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be pointed out that the described implementation examples 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.

[0030] The circumcision stapler of the present invention comprises a disposable consumable structure and a handle structure used in conjunction with the disposable consumable structure.

[0031] In this embodiment, see Figures 1 to 6 The disposable consumable structure includes a glans cover 10, a knife plate 20, a staple cartridge assembly 35, an anastomosis assembly 50, an outer cylinder 60, an elastic component 70, and a fixing ring 90. The front end of the glans cover 10 is a bell-shaped structure, and a connecting shaft is provided at the rear end of the glans cover 10. The connecting shaft has a guide groove 11. The knife plate 20 is arranged on the front end of the glans cover 10. The staple cartridge assembly 35 is fixedly connected to the outer cylinder 60. The interior of the anastomosis assembly 50 has a protrusion that matches the guide groove 11 on the connecting shaft, and the two move relative to each other along the axial direction.

[0032] In this embodiment, an elastic component 70 is provided at one end of the anastomosis component 50 away from the circumcision blade 52, one end of the elastic component 70 abuts against the step of the outer tube 60, and the other end abuts against the step of the fixing ring 90, so that the anastomosis component 50 is away from the glans hood 10, and the fixing ring 90 cooperates with a part of the inner wall of the outer tube 60, and the two move relative to each other along the axial direction. After the anastomosis component 50 axially penetrates the outer tube 60, it is fixedly connected with the fixing ring 90. Among them, one end of the elastic component 70 acts on the outer tube 60, and the other end acts on the fixing ring 90, so that the anastomosis component 50 is away from the glans hood 10; the elastic component 70 can ensure that the position of the component is relatively fixed, and ensure that the surgical requirements are met during the process of circumcision and suturing of the circumcision. In addition, the elastic component 70 is an elastic component with a certain elastic function, which can be a spring, rubber, etc., and those skilled in the art can use it according to actual needs.

[0033] In this embodiment, the rear end of the outer cylinder 60 is sleeved with a tailstock assembly, and the axis center of the tailstock assembly has a threaded hole 123 that matches with the rear end of the connecting shaft, and matches with the rear end thread of the connecting shaft. At least one tailstock through hole 122 is provided around the threaded hole 123, and the tailstock through hole 122 is connected to the push rod 211 of the handle structure, and the handle structure and the disposable consumable structure are detachably connected through at least one tailstock positioning structure 124 provided on the tailstock assembly.

[0035] The knife plate 20 of this embodiment is used to resist the blade when the circumcision cutter head 52 is cutting, so as to complete the cutting. Of course, the shape of the knife plate 20 is set to be annular, but it is not limited to annular, and other shapes are all OK, as long as it can be placed in the glans cover 10 and can achieve the purpose of limiting the circumcision cutter head 52. At the same time, the material of the knife plate 20 is used according to the choice of the user, such as being composed of a flexible or easily damaged material.

[0036] In this embodiment, the staple cartridge assembly 35 includes a staple plate 30 and a staple holder 40 . A plurality of staples are evenly arranged on the staple plate 30 , and a staple holder 40 is provided with staple grooves corresponding to the staples.

[0037] Specifically, the staple cartridge assembly 35 is fixed together with the outer tube 60. When in use, the anastomosis assembly 50 moves forward coaxially along the outer tube, and will push out the suture staples and the circular cutting blade head 52 at the same time. After the suture staples pass through the skin tissue, they will be bent and sutured by the staple groove 13 (similar to a stapler), and the circular cutting blade head 52 will cut at the same time (at this time, the skin tissue is located on the blade plate 20).

[0038] Among them, the structure of the suture nail plate 30, the suture nail seat 40, the suture nail and the suture nail groove can be similar to a U shape. The U-shaped nail fixes the foreskin after the cut inside and outside the foreskin. After the wound is fixed, wait for the cut wound to heal.

[0039] In this embodiment, the anastomosis assembly 50 includes a coaxially arranged pressure head 51 and a circular cutting head 52. The pressure head 51 and the circular cutting head 52 are fixedly connected to form the anastomosis assembly 50, and the cutting edge of the circular cutting head 52 is located on the inner side of the pressure head 51.

[0040] Among them, a protruding pressing nail head 514 is evenly arranged at the front end of the pressing head 51, corresponding to the suture nail on the suture nail seat 40.

[0041] The pressure head 51 has a cylindrical structure, and a protrusion 512 is provided inside the cylindrical structure to match with the guide groove 11 on the connecting shaft. When the two are matched, they can move relative to each other along the axial direction.

[0042] Furthermore, the outer wall of the cylindrical structure is provided with at least one guide groove 511, and part of the inner wall of the outer cylinder 60 is provided with a protrusion 601 that matches with the guide groove 511 of the outer wall of the cylindrical structure. When the two match, they can move relative to each other along the axial direction.

[0043] In this embodiment, the tailstock assembly includes a tailstock 120, and at least one fixed hook 80 is connected to the outer side of the tailstock 120. The fixed hook 80 is connected to the tailstock 120 through an overshaft 110. A torsion spring 100 is passed through the overshaft 110. The fixed hook 80 is bounced toward a direction close to the overshaft 110 due to the elastic force of the torsion spring 100.

[0044] join Figures 7 to 9 The handle structure includes a main shell composed of an upper shell 220 and a lower shell 340. A connecting head 200 and a pushing head 210 are provided at the opening of the main shell. The connecting head 200 and the pushing head 210 are coaxially assembled, and an axial rotation limiting structure is provided between the pushing head 210 and the connecting head 200.

[0045] Among them, at least one connector through hole 201 is provided on the connector 200, and at least one push rod 211 is provided on the push head 210, and the push rod 211 on the push head 210 is arranged in cooperation with the connector through hole 201 on the connector 200. It can be seen that the uniform distribution of multiple push rods 211 and connector through holes 201 can reduce the difficulty of processing, and the uniform distribution can ensure the uniform quality of the push rod 211 in the axial direction, and prevent the push rod 211 from tilting in the axial direction due to uneven quality, thereby affecting the accuracy and quality of processing.

[0046] A slot 203 is disposed on the outer side of the connector 200 near the connector through hole 201 , and a connector positioning structure 202 is disposed on the slot 203 .

[0047] The push head 210 has a threaded hole 212 at its axis, and a lead screw 240 is provided in cooperation with the threaded hole 212. When the lead screw 240 rotates, the push head 210 moves linearly along the axis, driving the glans hood 10 to move left and right to complete the cutting and suturing action. A bearing is installed at one end of the lead screw 240.

[0048] In this embodiment, a motor 290 is disposed in the main housing, the motor 290 is connected to one end of the lead screw 240 via a coupling 250 , and the connector 200 is fixedly connected to the motor 290 via a fixing sleeve 280 .

[0049] In this embodiment, a main control board 300 and a rechargeable battery 350 for providing power to the main control board 300 are disposed in the main housing, and the main control board 300 is drivingly connected to the motor 290 .

[0050] The motor 290 can be a linear motor with high positioning accuracy. Where linear motion is required, the linear motor can realize direct transmission, thereby eliminating various positioning errors caused by intermediate links, so the positioning accuracy is high. For example, if microcomputer control is adopted, the positioning accuracy of the entire device can be greatly improved.

[0051] In this embodiment, a plurality of function buttons and a power indicator light 310 are provided on the main control board 300, and the plurality of function buttons are electrically connected to the main control board 300. The main control board 300, the plurality of function buttons and the motor 290 are all electrically connected, that is, connected by wires, etc., and are certainly not limited to wire connections, as long as the connection method that conducts electrical signals is acceptable, such as wireless connection such as Bluetooth.

[0052] In this embodiment, the main control board 300 is provided with a charging contact structure 330 exposed on the surface of the main housing.

[0053] Specifically, the circumcision stapler of the present invention is composed of two parts: a disposable consumable structure and a driving handle structure.

[0054] Among them, the disposable consumables structure is a disposable sterile product, which mainly includes a glans cover 10, a knife plate 20, a staple magazine assembly 35, an anastomosis assembly 50, an outer tube 60, an elastic component 70, a fixing ring 90, a tailstock assembly, etc.

[0055] The front end of the glans cap 10 has a bell-shaped bowl-shaped structure, which fits the glans when in use. The rear end of the bowl-shaped structure has an elongated connecting shaft, which has at least one guide groove 11 or protrusion, and a threaded portion 12 at the rear end of the connecting shaft. A plurality of nail-retaining grooves 13 are evenly distributed on the edge of the bowl-shaped structure, and the number thereof corresponds to the number of suture nails.

[0056] The knife plate 20 is made of a flexible or breakable material.

[0057] A number of suture staples are evenly distributed on the suture staple plate 30 .

[0058] The staple holder 40 is provided with staple grooves corresponding to the number of staples.

[0059] The anastomosis assembly 50 is composed of a pressure head 51 and a circumcision blade head 52 which are coaxially fixed. The circumcision blade head 52 is in the shape of a thin-walled circular ring and has a sharp cutting edge. The cutting edge is made of a metal material, and the cutting edge is located on the inner side of the pressure head 51.

[0060] The pressing head 51 has a cylindrical structure, and the outer wall of the cylindrical structure has at least one guide groove 511 or protrusion. The interior of the cylindrical structure has a guide groove 512 or protrusion that matches the guide groove 11 on the connecting shaft of the glans cover 10. When the two are matched, they can move relative to each other along the axial direction, but cannot rotate relative to each other. One end of the pressing head 51 is distributed with a protruding pressure nail head 514, and the number of the pressure nail heads 514 corresponds to the number of suture nails.

[0061] The outer cylinder 60 has a cylindrical structure, and a part of the inner wall of the cylindrical structure has a guide groove 601 or a protrusion that matches the guide groove 511 on the outer wall of the pressure head 51. When the two are matched, they can move relative to each other along the axial direction, but cannot rotate relative to each other.

[0062] In this embodiment, the anastomosis assembly 50 is inserted into the outer tube 60 along the axial direction, the elastic component 70 is placed at the end away from the suture head 514, and the fixing ring 90 is bonded or screwed to the anastomosis assembly 50. At this time, one end of the elastic component 70 abuts against the step of the outer tube 60, and the other end abuts against the step of the fixing ring 90. The fixing ring 90 cooperates with a part of the inner wall of the outer tube 60 and can move along the axial direction. At this time, under the action of the elastic force of the elastic component 70, the assembly of the anastomosis assembly 50 and the fixing ring 90 will be maintained at the end of the outer tube 60 away from the suture nail.

[0063] The tailstock 120 is connected with at least one fixed hook 80 , which is connected to the tailstock 120 together with the overshaft 110 . The overshaft 110 is penetrated by a torsion spring 100 . The fixed hook 80 is rebounded toward the direction close to the overshaft 110 due to the elastic force of the torsion spring 100 .

[0064] The tailstock 120 has a threaded hole 123 at its axis center that can be matched with the threaded portion 12 at the rear end of the connecting shaft.

[0065] The tailstock 120 has at least one tailstock through hole 122 , and the push rod 211 of the handle structure can pass through the tailstock through hole 122 .

[0066] The tailstock 120 has at least one tailstock positioning structure 124, which can cooperate with the positioning structure to ensure that the push rod 211 of the handle structure can smoothly pass through the tailstock through hole 122 when pushed out, and the two connected parts will not rotate relative to each other when the handle structure and the consumable structure are quickly connected.

[0067] During assembly, the suture nail plate 30 is bonded together with the suture nail seat 40, the suture nail is placed in the suture nail groove, and then it is coaxially assembled together with the assembly consisting of the anastomosis component 50 and the outer tube 60. At this time, the pressure nail head 514 will be placed in the nail groove of the suture nail seat 40, but due to the elastic force of the elastic component 70, the pressure nail head 514 will be away from the suture nail by a certain distance without being affected by external force.

[0068] Then, the knife plate 20 is coaxially assembled with the glans cap 10 and coaxially inserted into the anastomosis assembly 50, and the tail seat 120 is tightened at the rear end to complete the assembly of the consumables.

[0069] Of course, in this embodiment, the entire disposable consumable structure can be designed into multiple models to adapt to the glans sizes of different patients.

[0070] The handle structure of this embodiment is a reusable part after being sterilized, and it mainly includes an upper shell 220, a lower shell 340, a connecting head 200, a push head 210, a screw 240, a motor 290, a coupling 250, a fixing sleeve 280, a main control panel 300, function buttons, etc.

[0071] The connector 200 has at least one connector through hole 201 and a connector positioning structure 202; when the handle structure and the disposable consumable structure are quickly connected, it can cooperate with the positioning structure to ensure that the push rod 211 of the handle structure can smoothly pass through the tail stock through hole 122 when pushed out, and the two connected parts will not rotate relative to each other.

[0072] The connector 200 has a slot 203, which ensures that when the handle structure and the consumable structure are quickly connected, the fixed hook 80 can lock the slot 203 to ensure that the two components are reliably connected and will not separate when subjected to axial thrust.

[0073] The push head 210 has at least one push rod 211, and the push head 210 and the connector 200 are coaxially assembled. The push rod 211 is placed in the connector through hole 201, and the push head 210 and the connector 200 have an axial rotation limiting structure so that the two can only move relative to each other in the axial direction and cannot rotate.

[0074] The axis of the push head 210 has a nut hole 212, which cooperates with the lead screw 240. When the lead screw 240 rotates, the push head 210 will move forward or backward along the axis. A bearing is installed at one end of the lead screw 240 to ensure stable rotation.

[0075] The motor 290 is connected to one end of the lead screw 240 via the coupling 250 and can drive the lead screw 240 to rotate forward and reverse.

[0076] The connector 200 is fixedly connected to the motor 290 via the fixing sleeve 280, which can ensure that the coaxial assembly of the components is firm and reliable.

[0077] In this embodiment, a plurality of function buttons and a power indicator light 310 are provided on the main control panel 300. Specifically, the main control panel 300 has at least a forward button 270. When triggered, the push head 210 will move forward, and the push rod 211 will extend from the connector through hole 201; a backward button 260. When triggered, the push head 210 will move backward, and the push rod 211 will retract from the connector through hole 201; and a safety button 320. When locked, at least the forward button 270 cannot be triggered. The power indicator light 310 can remind medical staff whether the existing power can complete the operation, and can also provide a charging reminder function for the rechargeable battery (charging or fully charged).

[0078] The main control board 300 also has charge and discharge protection and motor torque protection functions. The charge and discharge protection function can protect the service life of the rechargeable battery 350. The motor torque protection function can automatically stop the motor 290 when the output torque of the motor 290 is greater than the required value to protect the life of the motor 290 and the reliability of the entire handle structure. The main control board 300 can be composed of one or more circuit board cards.

[0079] The rechargeable battery 350 provides power for the entire handle structure.

[0080] The charging contact structure 330 is an exposed structure that can be in contact with a dedicated charging base to charge the handle structure and is easy to disinfect.

[0081] The upper shell 220 and the lower shell 340 provide a mounting base for the entire handle structure, while providing protection for the components of the handle structure. The external structure also provides a one-handed grip function for medical personnel.

[0082] In actual applications, the disposable consumables are sterile packaged and the appropriate model must be selected according to the size of the patient's glans.

[0083] After completing the preoperative preparation, the medical staff needs to open the sterile package, unscrew the tailstock 120, remove the glans cover 10, and use the glans cover 10 to press against the patient's glans, and cover the foreskin on the outside of the glans cover 10.

[0084] The foreskin is tied tightly with medical thread, the removed part of the consumables is assembled coaxially with the glans cover 10, and the tailstock 120 and the glans cover 10 are tightened.

[0085] The medical staff takes the sterilized handle structure and confirms whether the push rod 211 protrudes from the connector through hole 201. If it does, the back button 260 needs to be pressed to return the push rod 211 to the connector through hole 201; observe whether the safety button 320 is locked, if not, the safety button is locked.

[0086] After confirming the handle structure, the medical staff positions and connects the connector 200, the positioning structure, the card slot 203, the tailstock positioning structure 124 and the fixed hook 80 of the consumable structure.

[0087] After checking the connection, release the safety button 320 and trigger the forward button 270. At this time, the motor 290 drives the screw 240 to rotate through the coupling 250. The screw 240 cooperates with the nut hole 212 to drive the push head 210 to move forward and make the push rod 211 extend from the through hole.

[0088] At this time, the handle structure and the consumable structure are fixedly connected in a fixed position, and the push rod 211 will pass through the tailstock through hole 122 on the tailstock 120 and abut against the fixing ring 90. Because the fixing ring 90 and the anastomosis assembly 50 are bonded or threaded together, when the push rod 211 continues to move forward, the fixing ring 90 and the anastomosis assembly 50 will overcome the elastic force of the elastic component 70 due to the thrust of the push rod 211 and move forward, and the circumcision blade 52 will perform a circular cutting on the foreskin fastened to the outside of the glans hood 10, and at the same time, the protruding pressure nail head 514 on the pressure head 51 will push the suture nail to perform foreskin anastomosis.

[0089] After the cutting and anastomosis, the handle structure and the consumable structure are removed, the disposable consumable structure is disposed of as medical waste, and the handle structure is disinfected and charged to prepare for the next operation.

[0090] It can be seen that the present invention is mainly composed of a reusable handle driving part and a disposable consumable structure, which can reduce the operation time and reduce the pain of patients. At the same time, it can reduce the workload of medical staff, improve the operation effect, and have good economic efficiency.

[0091] It should be noted that "one embodiment", "another embodiment", "embodiment", "preferred embodiment" and the like mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the example included in at least one embodiment generally described in this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Further, when a specific feature, structure or characteristic is described in conjunction with any embodiment, it is claimed that the realization of such feature, structure or characteristic in conjunction with other embodiments also falls within the scope of the present invention. Although the present invention is described herein with reference to a plurality of illustrative examples of the present invention, it should be understood that those skilled in the art can design many other modifications and implementations that fall within the scope and spirit of the principles disclosed in this application. More specifically, within the scope of the present application disclosure, drawings and claims, in addition to the deformation and improvement that can be made to the components and / or layout of the subject combination layout, other uses will also be obvious to those skilled in the art.
