Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a bladder tumor dissector. Background Art

[0002] Bladder tumors refer to tumors that occur in the bladder. Bladder tumors can be divided into two categories: epithelial and non-epithelial tumors, which can be benign or malignant. Tumors of bladder epithelial origin include urothelial carcinoma, squamous cell carcinoma, and adenocarcinoma, accounting for more than 95% of all tumors. Non-epithelial bladder tumors include fibroma, leiomyoma, hemangioma, pheochromocytoma, etc., as well as rhabdomyosarcoma, chondroma, dermoid cysts, etc. that occur in ectopic tissues outside the bladder, which are extremely rare.

[0003] In the prior art, bladder tumors are generally cut by laser cutting devices. Since laser cutting is a point-shaped energy ring cutting, the cut part of the tumor will collapse during the cutting process, thereby blocking the field of view, so that the quality of tumor cutting cannot be guaranteed. Therefore, a bladder tumor clearer is designed to improve the above problem. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a bladder tumor dissecting device.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A bladder tumor clearer is used in conjunction with an endoscope and a laser cutting device, comprising a placement tube, an operating part and a clearing part. The clearing part comprises a fixed tube screwed onto the placement tube, two movable arms that cooperate with each other are hinged onto the fixed tube, and the two movable arms are connected at one end away from the placement tube by an elastic transparent film material; the operating part comprises an assembly tube screwed onto the placement tube, a fixed arm is provided on the assembly tube, and a pulling arm is hinged onto the fixed arm. A wiring channel is formed between the placement tube, the fixed tube and the assembly tube, and the two movable arms are connected to the pulling arm by a transmission mechanism that passes through the wiring channel. The two movable arms are opened by pulling the transmission mechanism through the movable arms. After the two movable arms are opened, the transparent film material is stretched to form a barrier component together with the movable arms. At this time, the position of the barrier component is changed by the placement tube, so that the collapsed part during the tumor cutting process is pushed away, thereby exposing the uncut part of the tumor.

[0007] Preferably, magnetic blocks are provided on adjacent surfaces of the two movable arms, and assembly grooves for arranging the magnetic blocks are provided on the movable arms, so that the two movable arms can be automatically closed after the tumor cutting is completed.

[0008] Preferably, the two movable arms have an arrangement groove at one end away from the arrangement tube, the two ends of the transparent film material are respectively fixed in the two arrangement grooves, and the surface of the arrangement groove close to the fixed tube is an inclined surface, so as to avoid friction damage between the transparent film material and the arrangement groove during the stretching process of the transparent film material.

[0009] Preferably, the transmission mechanism includes a first pull wire connected to the pulling arm and passing through the assembly cylinder and the arrangement cylinder in sequence, and a second pull wire located in the fixed cylinder and respectively connected to the two movable arms. The second pull wire is detachably connected to the first pull wire through a connecting mechanism. The connecting mechanism includes a mother component connected to the first pull wire and a child component connected to the second pull wire. The mother component and the child component are detachably connected through a hook and a hanging hole, which facilitates the disassembly and assembly of the arrangement cylinder, the operating part and the clearing part.

[0010] Preferably, the transmission mechanism also includes a reset mechanism that cooperates with the mother part, the reset mechanism includes a reset spring and a partition fixed in the arrangement tube, and an active cavity is formed in the arrangement tube along the partition to one end for installing the clearing part, the mother part and the reset spring are both placed in the active cavity, and the two ends of the reset spring are respectively against the mother part and the partition, the first pull wire passes through the partition and is connected to the mother part after passing through the reset spring, so that the pulling arm can automatically reset after the tumor cutting is completed.

[0011] Preferably, sliding grooves are provided on the cavity wall of the movable cavity and on the cylinder wall of the fixed cylinder, the edges of the mother component and the child component have sliding blocks that cooperate with the sliding grooves, the hooks and the hanging holes are rotatably connected to the mother component and the child component respectively, during the assembly of the clearing part and the arrangement cylinder, the problem of damage to the first pull wire and the second pull wire due to torque is avoided.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention has a simple structure and is easy to use. The pulling arm pulls the transmission mechanism to drive the two movable arms to open. After the two movable arms are opened, the transparent film material is stretched and forms a barrier component together with the movable arms. By changing the position of the barrier component, the collapsed part during the tumor cutting process can be pushed away, thereby exposing the uncut part of the tumor to the field of vision, which is convenient for the laser cutting device to perform tumor cutting later.

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example 1

[0022] like Figure 1 The bladder tumor clearing device shown in the figure is used in conjunction with an endoscope B and a laser cutting device C, including a placement tube 1, an operating part 2 and a clearing part 3. Specifically, the clearing part 3 includes a fixed tube 31 screwed on the placement tube 1, and two movable arms 32 that cooperate with each other are hinged on the fixed tube 31. The two movable arms 32 are connected at one end away from the placement tube 1 by an elastic transparent film material 33. The transparent film material 33 is an elastic transparent film material disclosed in Chinese patent application number CN202220835203.2. When the two movable arms 32 are opened, the transparent film The material 33 is stretched under force and forms a barrier component together with the two movable arms 32; the operating part 2 includes an assembly cylinder 21 screwed on the arrangement cylinder 1, a fixed arm 22 is provided on the assembly cylinder 21, and a pulling arm 23 is hinged on the fixed arm 22. A wiring channel is formed between the arrangement cylinder 1, the fixed cylinder 31 and the assembly cylinder 21, and the two movable arms 32 and the pulling arm 23 are connected by a transmission mechanism 4 that penetrates the wiring channel. The pulling arm 23 and the fixed arm 22 are equivalent to a lever. Moving the pulling arm 23 can pull the transmission mechanism 4 to open the two movable arms 32. In specific implementation, Figure 5As shown, the target tube A is first arranged along the patient's urethra, and then the endoscope B, the laser cutting device C and the bladder tumor dissecter disclosed in this embodiment are arranged into the patient's bladder through the target tube A. When performing tumor cutting, the endoscope B is used to feedback the operation progress to the medical staff, and the laser cutting device C is used to cut the tumor. When the cut part of the tumor collapses and blocks the surgical field of view, the part blocking the surgical field of view is located by the endoscope B, and the bladder tumor dissecter is moved close to the part blocking the surgical field of view. The transmission mechanism 4 is pulled by the pulling arm 23 to drive the two movable arms 32 to open. After the two movable arms 32 are opened, the transparent film material 33 is stretched to form a barrier component together with the movable arm 32. By changing the position of the barrier component, the collapsed part of the tumor during cutting can be pushed away, so that the part of the tumor that is not cut can be exposed to the field of view, thereby facilitating the medical staff to perform tumor cutting operations through the laser cutting device C.

[0023] As a preferred solution of the above embodiment, Figure 2 As shown, magnetic blocks 5 are provided on adjacent surfaces of the two movable arms 32, and assembly grooves for arranging the magnetic blocks 5 are opened on the movable arms 32. After the tumor cutting is completed, the force applied to the pulling arm 23 is unloaded, and the force for stretching the transparent film material 33 also disappears, and the stretched transparent film material 33 is reset. During this process, the two movable arms 32 approach each other. After the two movable arms 32 approach each other, the two magnetic blocks 5 attract each other to make the two movable arms 32 close to each other, so that the two movable arms 32 are automatically closed.

[0024] The two movable arms 32 are provided with a placement groove 34 at one end away from the placement tube 1, and the two ends of the transparent film material 33 are respectively fixed in the two placement grooves 34. Considering that the transparent film material and the placement groove are prone to friction damage during the stretching process of the transparent film material, further, the surface of the placement groove 34 close to the fixed tube 31 is an inclined surface, so that the transparent film material avoids the placement groove during the stretching process.

[0025] The transmission mechanism 4 includes a first pull wire 41 connected to the pulling arm 23 and passing through the assembly tube 21 and the arrangement tube 1 in sequence, and a second pull wire 42 located in the fixed tube 31 and connected to the two movable arms 32 respectively. The second pull wire 42 is detachably connected to the first pull wire 41 through a connecting mechanism 43. The connecting mechanism 43 includes a mother component 431 connected to the first pull wire 41 and a connecting sub-component 432 connected to the second pull wire 42. The mother component 431 and the sub-component 432 are detachably connected through a hook and a hanging hole, so that the arrangement tube 1 and the clearing part 3 can be detachably connected.

[0026] Example 2

[0027] After the tumor is cut, in order to make the pulling arm automatically reset, further, as Figure 2-3As shown, the transmission mechanism 4 also includes a reset mechanism 44 that cooperates with the mother component 431. The reset mechanism 44 includes a reset spring 441 and a partition 442 fixed in the arrangement tube 1. An active cavity 11 is formed in the arrangement tube 1 along the partition 441 to one end for installing the clearing part 3. The mother component 431 and the reset spring 441 are both placed in the active cavity 11, and the two ends of the reset spring 441 are respectively against the mother component 431 and the partition 441. The first pull wire 41 passes through the partition 442 and is connected to the mother component 431 after passing through the reset spring 441. During the operation of the blocking component, the reset spring 441 is in a compressed state. After the tumor cutting is completed and the force applied to the pulling arm 23 is unloaded, the reset spring 441 in the compressed state is reset. During this process, the reset spring 441 pushes the mother component 431 away from the operating part 2. At this time, the mother component 431 pulls the first pull wire 41 to automatically reset the pulling arm 23.

[0028] Example 3

[0029] In the process of disassembling and assembling the arrangement tube 1 and the clearing part 3, in order to avoid the problem that the first pull wire 41 and the second pull wire 42 are damaged due to the torque, further, as Figure 4 As shown, a slide groove 6 is provided on the cavity wall of the movable cavity 11 and the cylinder wall of the fixed cylinder 31, and the edges of the mother component 431 and the child component 432 are provided with a slider 7 which cooperates with the slide groove 12, and the hook and the hanging hole are rotatably connected to the mother component 431 and the child component 432 respectively. Specifically, during the disassembly and assembly of the arrangement cylinder 1 and the clearing portion 3, the setting of the slide groove 6 and the slider 7 prevents the mother component 431 and the child component 432 from rotating, so the first pull wire 41 and the second pull wire 42 will not generate torque, and the rotatable hook and hanging hole ensure that the arrangement cylinder 1 and the clearing portion 3 will not be unable to be disassembled and assembled due to the inability of the mother component 431 and the child component 432 to rotate during the disassembly and assembly.

[0030] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
