Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a resectoscope handle, and also to a resectoscope and a method for using the resectoscope. Background Art

[0002] A resectoscope is a medical device clinically applicable for minimally invasive surgeries such as cutting or coagulating target tissues by using a high-frequency device to output energy to an electrode through a natural body passage of a human body to reach a lesion site under direct vision of an endoscope. It is commonly used in surgical treatments for diseases such as prostate hyperplasia, uterine fibroids, and bladder tumors. A resectoscope mainly consists of an endoscope, a handle, and a sheath. Among them, the handle is one of the important components connecting the endoscope, the electrode, and the sheath. During the surgical process, a doctor performs various operations through the handle.

[0003] With the development of technology, in resectoscopic surgeries, mounting the resectoscope on the actuator of a surgical robot and allowing a doctor to remotely control the surgical robot and then operate the resectoscope to perform surgical treatment on a patient are increasingly applied. However, existing resectoscope handles are designed according to an ergonomic shape. For example, the resectoscope handles disclosed in Patent CN201720322051 and Patent CN201822257693 have an outer shape structure composed of a grip, a thumb ring, a slider, and a handle body. Both the grip and the thumb ring are necessary components for facilitating human hand operation. Due to the significant structural differences between the actuator of a surgical robot and a human hand, when used in conjunction with a surgical robot, the complex outer shapes of the grip and the thumb ring will cause inconvenience in mounting to the actuator. A handle structure without a grip and a thumb ring can be more easily mounted to the actuator, but such a handle structure is not suitable for human hand operation.

[0004] Due to potential risks of malfunctions caused by uncontrollable factors during the use of a surgical robot, when the surgical robot malfunctions and cannot continue to work, it is necessary to replace the handle of the resectoscope with a handle suitable for human hand operation and have the doctor continue to perform the surgery. When replacing the handle, the electrode needs to be disassembled from the handle suitable for the robot and then installed on the handle suitable for human hand operation. Since the electrode is a surgical execution component that contacts the patient, such a conversion process is relatively troublesome and time-consuming, and involves the disassembly and assembly of the electrode, which poses a greater risk to the patient. Summary of the Invention

[0005] In order to overcome the above deficiencies of the prior art, the present invention provides a resectoscope handle, and also provides a resectoscope and a method for using the resectoscope, which solves the problem that the current resectoscope handle cannot be used both for a surgical robot and human hand operation in one aspect.

[0023] One of the beneficial effects of the present invention is as follows:

[0024] According to one aspect of the present disclosure, this resectoscope adopts the handle of this resectoscope. Since both the handle grip and the grip ring of the handle of this resectoscope can be installed or detached from the handle body, according to the usage method of this resectoscope, the handle of the resectoscope can be assembled into two different states suitable for surgical robots and human hands according to the usage requirements. When it is necessary to use a surgical robot to operate the resectoscope for surgery, the handle grip and the grip ring can be not assembled to the handle body, which is convenient for the assembly of the handle of the resectoscope with the actuator of the surgical robot, and also avoids the complex shape of the handle grip and the grip ring from interfering with the movement of the surgical robot, facilitating the actuator to control the resectoscope. When a failure occurs to the surgical robot or other situations occur during the surgery and it is necessary to switch to the doctor to operate the resectoscope to continue the surgery, the handle of the resectoscope can be detached from the actuator of the surgical robot, and then the handle grip and the grip ring can be assembled to the handle body to adapt to the operation of the resectoscope by hand. During this conversion process, there is no need to disassemble and assemble the electrode, so the conversion process is more simple, efficient, and safe, which can greatly reduce the risk of surgery and ensure the safety of the patient.

[0034] Refer to Figure 1 and Figure 2 The present invention discloses a resectoscope, including an endoscope assembly 5, a sheath assembly 6, an electrode 7, and the following resectoscope handle. The sheath assembly 6 and the endoscope assembly 5 are respectively installed at the front and rear ends of the tube column 12. The rear end of the electrode 7 is connected to a slider 13, and the slider 13 can slide along the axial direction of the tube column 12 to drive the electrode 7 to move back and forth. The slider 13 is provided with an electrode mounting round hole 131, and the rear end of the electrode 7 is installed in the electrode mounting round hole 131.

[0035] The present invention also discloses a method for using the above resectoscope, which specifically includes the following steps:

[0036] When the resectoscope is operated by a surgical robot, the handle 2 and the grip ring 3 are both in a state of being detached from the handle body 1. The handle body 1 is installed on the actuator of the surgical robot, and the actuator drives the slider 13 to slide along the axial direction of the tube column 12 to drive the electrode 7 to move back and forth;

[0037] When the resectoscope is operated by hand, the handle 2 and the grip ring 3 are both in a state of being installed on the handle body 1. The grip ring 3 is operated by hand to drive the slider 13 to slide along the axial direction of the tube column 12 to drive the electrode 7 to move back and forth.

[0038] Refer to Figures 3 - 5 The present invention also discloses a resectoscope handle, including a handle body 1, a handle 2, and a grip ring 3. The grip ring 3 can be installed or detached from the handle body 1. The handle body 1 includes a tube column 12 and a slider 13 sleeved on the tube column 12. The slider 13 can slide along the axial direction of the tube column 12. The handle 2 can be installed or detached from the tube column 12. When the grip ring 3 is installed on the handle body 1, the grip ring 3 can directly or indirectly drive the slider 13 to slide.

[0039] Specifically, the present resectoscope adopts the present resectoscope handle. Since the grip 2 and the grip ring 3 of the present resectoscope handle can be installed or detached from the handle body 1, according to the use method of the present resectoscope, the resectoscope handle can be assembled into two different states suitable for a surgical robot and a human hand according to the use requirements. When a surgical robot is required to operate the resectoscope for surgery, the grip 2 and the grip ring 3 can be not assembled to the handle body 1, which is convenient for the resectoscope handle to be assembled with the actuator of the surgical robot, and also avoids the complex shape of the grip 2 and the grip ring 3 interfering with the action of the surgical robot, which is convenient for the actuator to control the resectoscope; when the surgical robot fails or other conditions occur during the operation, and the doctor needs to operate the resectoscope to continue the operation, the resectoscope handle can be detached from the actuator of the surgical robot, and then the grip 2 and the grip ring 3 are assembled to the handle body 1 to adapt to the human hand to operate the resectoscope. In this conversion process, there is no need to disassemble and assemble the electrode, so the conversion process is simpler, more efficient, and safer, which can greatly reduce the risk of surgery and ensure the safety of patients.

[0040] See also Figures 3 - 5 The specific structure of the detachable handle 2 is that the handle body 1 includes a joint 11 fixed to the pipe column 12, and a slot 112 is provided on the side of the joint 11. The handle 2 includes a handle body 21 and a sleeve 25 fixed to the handle body 21. The sleeve 25 is provided with a clamp 22. When the handle 2 is installed on the pipe column 12, the joint 11 is inserted into the sleeve 25, and the clamp 22 is inserted into the slot 112. That is, the pipe column 12 is connected to the handle 2 through the joint 11, and the clamp 22 can move in a direction away from the central axis of the sleeve 25 to exit the slot 112. In this way, the sleeve 25 is sleeved on the joint 11, and the clamp 22 is inserted into the slot 112, so that the handle 2 can be fixedly installed; the clamp 2 is withdrawn from the slot 112, and the joint 11 is pulled out of the sleeve 25, so that the handle 2 can be disassembled. The disassembly operation is simple and convenient to use.

[0041] Specifically, there are many structures for realizing the movable clamp 22. For example, the clamp 25 itself is an elastic member, and the clamp 22 is fixedly arranged on the inner side of the clamp 25. When the handle 2 is installed on the pipe column 12, the clamp 25 is sleeved on the outside of the joint 11, and the clamp 22 is inserted into the slot 112 under the elastic force of the clamp 25 itself. When the handle 2 needs to be disassembled, it is only necessary to bend the clamp 25 toward the outside of the clamp 25 to disengage the clamp 22 from the slot 112, and the clamp 25 can be separated from the joint 11, which is simple to operate. Among them, the "inside of the clamp 25" refers to the side close to the central axis of the clamp 25, which is the side that will contact the joint 11, and the "outside of the clamp 25" refers to the side away from the central axis of the clamp 25.

[0042] In this embodiment, the structure for realizing the movable clamp 22 is that the clamping sleeve 25 is provided with an installation groove, the clamping member 22 is placed in the installation groove, and a positioning spring 23 is provided between the clamping member 22 and the clamping sleeve 25, and the positioning spring 23 can drive the clamping member 22 to move in a direction close to the central axis of the clamping sleeve 25. When the clamping sleeve 25 is sleeved on the outside of the joint 11, the clamping member 22 is inserted into the clamping slot 112 under the elastic force of the positioning spring 23, and the clamping connection is firm and safe to use.

[0043] See also Figure 6 and Figure 7 The specific structure for realizing the movable clamp 22 is that the clamp 22 includes a clamp block 223 and a force block 222 connected to each other, the clamp block 223 and the force block 222 form an L-shaped block, the force block 222 is provided with a spring slot, a stopper 27 is provided in the installation slot, the positioning spring 23 is placed in the spring slot, one end of the positioning spring 23 abuts against the stopper 27, and the other end of the positioning spring 23 abuts against the slot wall of the spring slot, and the positioning spring 23 can drive the clamp block 223 to move in the direction close to the central axis of the sleeve 25. When the handle 2 is in a natural state where it is not installed, due to the elastic force of the positioning spring 23, a part of the clamp block 223 is located in the inner hole of the sleeve 25, and the inner hole of the sleeve 25 is the space surrounded by the sleeve 25, which is the hole for the connector 11 to be inserted and installed.

[0044] Furthermore, in order to facilitate the moving of the clamping member 22 when the handle 2 needs to be removed, a shift block 26 is fixedly provided on one side of the force block 222, and the shift block 26 is located outside the clamping sleeve 25. By moving the shift block 26, the shift block 26 can drive the clamping block 223 to move toward or away from the central axis of the clamping sleeve 25.

[0045] Moreover, in order to limit the range of movement of the clamp 22, the clamp 22 is provided with a first limiting portion, and the clamp sleeve 25 is correspondingly provided with a second limiting portion, and the first limiting portion and the second limiting portion cooperate with each other to limit the range of movement of the clamp 22 in the installation slot. For example, the first limiting portion and the second limiting portion are both limiting blocks or limiting surfaces, and when the clamp 22 moves to the extreme position close to or away from the central axis of the clamp sleeve 25, the first limiting portion will abut against the second limiting portion, thereby limiting the range of movement of the clamp 22.

[0046] In this embodiment, the first limiting portion includes a waist-shaped hole 221 formed in the clamping member 22, and the second limiting portion includes a positioning pin 24 fixedly provided on the socket 25. The positioning pin 24 is inserted into the waist-shaped hole 221, and the positioning pin 24 and the waist-shaped hole 221 are in clearance fit. The positioning pin 24 can slide in the waist-shaped hole 221 to move the clamping member 22 in a direction close to or away from the central axis of the socket 25. The structure is simple and the limiting effect is good. In this embodiment, there are two waist-shaped holes 221 and two positioning pins 24. The two waist-shaped holes 221 are parallel to each other, and the two positioning pins 24 are fixedly provided on the side wall of the installation groove. The number of the waist-shaped holes 221 and the positioning pins 24 is two, which can prevent the clamping member 22 from rotating in the installation groove and ensure the moving direction of the clamping member 22.

[0047] Specifically, the joint 11 covers a part of the pipe column 12, specifically, the joint 11 covers the front end of the pipe column 12, and the pipe column 12 behind the joint 11 is exposed. The slider 13 is sleeved on the pipe column 12, and the slider 13 is located behind the joint 11. The socket 25 is a U-shaped sleeve, the opening width of the U-shaped sleeve is greater than the diameter of the pipe column 12, and one end of the U-shaped sleeve is connected to the handle body 21. When it is necessary to remove the handle 2, the clamping member 22 is withdrawn from the card slot 112, and the U-shaped sleeve is moved axially along the pipe column 12 and backward until it is separated from the joint 11. Then, the exposed pipe column 12 can be taken out from the opening of the U-shaped sleeve, which is convenient for the disassembly of the handle 2.

[0048] Furthermore, in order to prevent the U-shaped sleeve from rotating relative to the joint 11, a first positioning surface 251 is provided on the inner side of the U-shaped sleeve, and a second positioning surface 111 is correspondingly provided on the side surface of the joint 11. The second positioning surface 111 is parallel to the central axis of the pipe column 12, and the cross-section of the joint 11 at the second positioning surface 111 is a D-shaped cross-section. When the handle 2 is installed on the pipe column 12 and the U-shaped sleeve is sleeved on the joint 11, the first positioning surface 251 and the second positioning surface 111 are in contact to limit the rotation of the socket 25 relative to the joint 11.

[0049] Moreover, an inclined first guiding surface 113 is provided at the rear end of the joint 11, and an inclined second guiding surface is correspondingly provided on the inner side of the clamping block 223. When the first guiding surface 113 and the second guiding surface are in contact, the first guiding surface 113 can apply a force to the second guiding surface to move the clamping block 223 in a direction away from the central axis of the socket 25.

[0050] In this way, when the handle 2 is assembled onto the joint 11, first, the ferrule 25 is sleeved onto the exposed pipe column 12, then the ferrule 25 is axially moved forward. Next, the second guiding surface of the locking block 223 contacts the first guiding surface 113 of the joint 11. Continuing to push forward, under the action of the first guiding surface 113 and the second guiding surface, the locking block 223 will move away from the central axis of the joint 11 in the installation groove until the locking block 223 reaches the position of the card slot 112. Under the action of the positioning spring 23, the locking block 223 is inserted into the card slot 112, and the first positioning surface 251 and the second positioning surface 111 are in contact, thus fixing the handle 2 on the joint 11. When it is necessary to remove the handle 2, only need to toggle the block 26 to move the locking block 223 away from the central axis of the joint 11, so that the locking block 223 disengages from the card slot 112, and then move the ferrule 25 backward to disengage the ferrule 25 from the joint 11. Finally, separate the pipe column 12 from the ferrule 25 through the opening of the ferrule 25.

[0051] See Figure 3 and Figure 4 The handle body 1 further includes a push frame 14 and a reset member 17. The push frame 14 is connected to the slider 13. The grip ring 3 is rotatably connected to the push frame 14. The grip ring 3 can drive the slider 13 to slide through the push frame 14, and the reset member 17 can drive the slider 13 to slide in a direction away from the installation position of the handle 2.

[0052] Specifically, the grip ring 3 is rotatable rather than fixedly connected to the push frame 14 to adapt to different hands. Because when different people operate or the slider is in different positions, the angles of the fingers holding the grip ring 3 are different. Such a design can greatly increase the universality of the crowd, and improve the comfort and smoothness of the operator, and can reduce accidents.

[0053] Furthermore, there are various structures for the reset member 17 to drive the slider 13. For example, the push frame 14 is fixedly connected to the slider 13, the reset member 17 is a spring, the spring is sleeved on the pipe column 12, and one end of the spring is connected to the slider 13. When the spring is a compression spring, the compression spring is located in front of the slider 13. Specifically, in the structure of this embodiment, the compression spring is located between the joint 11 and the slider 13, and both ends of the compression spring respectively abut against the joint 11 and the slider 13. When the spring is a tension spring, the tension spring is located behind the slider 13, and the tension spring is located between the slider 13 and the rear end of the pipe column 12, and both ends of the tension spring are respectively fixedly connected to the slider 13 and the rear end of the pipe column 12. In the natural state, under the action of the spring, the slider 13 is located at the rear part of the pipe column 12, and the front end of the electrode 7 is retracted in the sheath assembly 6.

[0054] In this embodiment, the structure in which the reset member 17 drives the slider 13 is that the handle body 1 further includes a fixing bracket 15. The slider 13 is located between the joint 11 and the fixing bracket 15. One end of the fixing bracket 15 and one end of the pushing bracket 14 are hinged by a connecting shaft 16. The reset member 17 is a torsion spring. The torsion spring is sleeved on the connecting shaft 16. Two ends of the torsion spring are respectively connected to the fixing bracket 15 and the pushing bracket 14. The other end of the fixing bracket 15 is hinged to the pipe column 12. The middle part of the pushing bracket 14 is hinged to the slider 13. The grip ring 3 can be threadedly connected to the other end of the pushing bracket 14.

[0055] In this way, when the grip ring 3 is installed on the pushing bracket 14, by pushing the pushing bracket 14 forward through the grip ring 3, the slider 13 can be driven to slide forward along the pipe column 12. The slider 13 drives the electrode 7 to move forward. When the slider 13 moves to abut against the joint 11, it is the limit position of moving forward. When the driving force is released, the reset member 17 directly pushes the slider 13, or the reset member 17 pushes the slider 13 through the pushing bracket 14 to move backward for resetting. The slider 13 drives the electrode 7 to move backward.

[0056] Specifically, there are various structures for the rotatable grip ring 3. For example, the pushing bracket 14 is correspondingly provided with a connection hole. One side of the grip ring 3 is provided with a rotating shaft. The rotating shaft is inserted into the connection hole, and the diameter of the connection hole is slightly larger than the diameter of the rotating shaft. An anti - detachment block is screwed on the other side of the rotating shaft to prevent the rotating shaft from detaching from the connection hole. The grip ring 3 can rotate around the axial direction of the connection hole. Unscrew the anti - detachment block, and the grip ring 3 can be removed.

[0057] See Figure 8 , in this embodiment, the structure in which the grip ring 3 is rotatable is that the grip ring 3 is connected to the pushing bracket 14 through a connection lock 4. One end of the connection lock 4 is provided with an installation hole. The inner wall of the installation hole is provided with a first annular groove along the circumferential direction. One side of the grip ring 3 is provided with a connection shaft 31. The diameter of the installation hole is larger than the diameter of the connection shaft 31. A second annular groove is provided along the circumferential direction on the outer edge of the connection shaft 31. A snap ring 32 is clamped in the second annular groove. The snap ring 32 is a C - shaped snap ring. The connection shaft 31 is inserted into the installation hole. The snap ring 32 is inserted into the first annular groove. The grip ring 3 can rotate around the axial direction of the installation hole. The other end of the connection lock 4 is provided with a stud 41. The pushing bracket 14 is correspondingly provided with a threaded hole 141. The stud 41 can be installed in the threaded hole 141. By screwing the stud 41 into or out of the threaded hole 141, the grip ring 3 can be installed or detached from the pushing bracket 14, which is convenient for disassembly and assembly.

[0058] As can be seen from the above structure, both the handle 2 and the grip ring 3 have the function of quick disassembly and assembly. The electrosurgical mirror handle can be quickly switched between two states, so that in the occasion where both manual and surgical robot operations are required simultaneously, the handle 2 and the grip ring 3 can be quickly installed and disassembled to respectively adapt to the human hand and the surgical robot.
