Description

Technical Field

[0001] This application relates to the field of medical device technology. More specifically, this application relates to a medical water jet transmission device. Background Technology

[0002] A water jet is a device that uses a high-pressure water jet for cold cutting. In the field of medical devices, water jets can be used to cut human tissue to eliminate lesions. The medical water jet drive mechanism is the device that drives the water jet to rotate or reciprocate linearly. In practical applications, when the water jet is near a lesion, the medical water jet drive mechanism can drive the water jet to rotate and cut human tissue, either near or far from the lesion, thus automating the water jet operation.

[0003] Traditional medical water jet drive mechanisms are simple in structure and have limited functionality. For example, Chinese invention patent application CN114587512A discloses a medical water jet instrument and system. The drive mechanism of this instrument includes a drive mechanism and a transmission component. The transmission component comprises a first gear and a second gear, which are meshed together. The first gear is connected to the water jet, and the second gear is connected to the drive mechanism. The drive mechanism drives the second gear to rotate, which in turn drives the first gear to rotate, thus enabling the first gear to rotate the water jet. This type of drive mechanism has no structural connection to the endoscope; it only functions to rotate the water jet and cannot move the water jet forward or backward from the nozzle, nor can it move the endoscope along with the water jet. This causes inconvenience for medical personnel. Summary of the Invention

[0004] The purpose of this application is to provide a medical water jet transmission device, solving the technical problem of how to move the water jet and endoscope together in front of or behind the water jet nozzle while rotating the water jet. This application is mainly achieved through the following technical solutions:

[0005] This application provides a medical water jet transmission device, including:

[0006] The system comprises a first drive mechanism, a second drive mechanism, a first transmission assembly, a second transmission assembly, a first connecting member, a second connecting member, and a first horizontal moving mechanism, wherein...

[0007] One end of the first transmission component is connected to the first drive mechanism, and the other end is connected to the first connecting member; one end of the second transmission component is connected to the second drive mechanism, and the other end is connected to the first horizontal moving mechanism; the first horizontal moving mechanism is connected to the water jet and the endoscope; the second connecting member is sleeved on the outer wall of the water jet; the first connecting member is connected to the second connecting member;

[0008] When the first drive mechanism drives the first transmission component to move, the first transmission component drives the first connecting member to rotate, the first connecting member drives the second connecting member to rotate, and the second connecting member drives the water jet to rotate.

[0009] When the second drive mechanism drives the second transmission component to move, the second transmission component drives the first horizontal moving mechanism to move, and the first horizontal moving mechanism drives the water jet and the endoscope to move in front of or behind the nozzle of the water jet.

[0010] The medical water jet transmission device provided in this application embodiment connects one end of a first transmission component to a first driving mechanism and the other end to a first connecting member. The first connecting member is connected to a second connecting member, which is sleeved on the outer wall of the water jet. Thus, the first driving mechanism can drive the first transmission component to move, the first transmission component drives the first connecting member to rotate, the first connecting member drives the second connecting member to rotate, and the second connecting member drives the water jet to rotate. Based on this structure, this application embodiment further connects one end of the second transmission component to the second driving mechanism and the other end to a first horizontal moving mechanism. The first horizontal moving mechanism is connected to the water jet and the endoscope. Thus, the second driving mechanism can drive the second transmission component to move, the second transmission component drives the first horizontal moving mechanism to move, and the first horizontal moving mechanism drives the water jet and the endoscope to move in front of or behind the water jet nozzle. Therefore, the medical water jet transmission device provided in this application embodiment can simultaneously rotate the water jet and drive the water jet and the endoscope to move in front of or behind the water jet nozzle.

[0011] The first connecting member is a cylindrical spur gear, and the second connecting member is a first gear, wherein the cylindrical spur gear meshes with the first gear.

[0012] The engagement of the cylindrical spur gear with the first gear can improve the smoothness and reliability of the water jet rotation.

[0013] The first horizontal moving mechanism includes a first lead screw, a lead screw nut, and a guide member. The first lead screw is connected to the second transmission assembly. The lead screw nut is sleeved on the outer side wall of the first lead screw. The guide member is connected to the lead screw nut. The water jet and the endoscope are respectively connected to the guide member.

[0014] When the second transmission component drives the first lead screw to rotate, the lead screw nut drives the guide to move linearly on the first lead screw, and the guide drives the water jet and the endoscope to move in front of or behind the water jet nozzle.

[0015] The structure of the first horizontal moving mechanism can effectively drive the water jet and endoscope to move together in front of or behind the water jet nozzle.

[0016] The guide is composed of a C-shaped structure and a cylindrical body, the water jet is placed on the C-shaped structure, and the endoscope is placed inside the cylindrical body.

[0017] By placing the water jet and endoscope on the same guide, the water jet can be moved while the endoscope moves, making it easier for medical staff to operate.

[0018] The guide structure allows the endoscope to be placed close to the water jet, enabling medical staff to directly observe the patient's lesions and the position of the water jet nozzle during surgery, thus increasing the safety of the operation.

[0019] The medical water jet transmission device also includes a first housing, and the first connector and the first lead screw are disposed inside the first housing.

[0024] The first through hole, the second through hole, the first fixed base, and the second fixed base are provided to fix the positions of the cylindrical spur gear and the first lead screw, preventing the cylindrical spur gear and the first lead screw from interfering with each other.

[0025] The medical water jet transmission device also includes a second housing, in which the first drive mechanism and the second drive mechanism are partially disposed.

[0026] The second housing helps prevent damage to the first and second drive mechanisms from external equipment and also serves as a dustproof feature.

[0027] The second housing is provided with a third through hole and a fourth through hole. The first drive mechanism passes through the third through hole and is connected to the first transmission component, and the second drive mechanism passes through the fourth through hole and is connected to the second transmission component.

[0028] The third and fourth through holes can restrict the positions of the first and second drive mechanisms, preventing them from interfering with each other.

[0029] The medical water jet transmission device further includes a third drive mechanism, a third transmission component, and a second horizontal movement mechanism. One end of the third transmission component is connected to the third drive mechanism, and the other end is connected to the second horizontal movement mechanism. The second horizontal movement mechanism is connected to the water jet.

[0030] When the third drive mechanism drives the third transmission component to move, the third transmission component drives the second horizontal moving mechanism to move, and the second horizontal moving mechanism drives the water jet to move in front of or behind the nozzle of the water jet.

[0031] The third drive mechanism, the third transmission assembly, and the second horizontal movement mechanism enable the water jet to move independently in front of or behind the nozzle.

[0032] The second horizontal moving mechanism includes a second lead screw and a lead screw slide. The second lead screw is connected to the third transmission assembly, and the lead screw slide is sleeved on the second lead screw and connected to the water jet.

[0033] The lead screw slide has at least one protrusion, and each of the protrusions engages with the water jet.

[0034] The raised part on the lead screw slide reduces the contact area between the lead screw slide and the water jet, thus preventing wear on the water jet.

[0035] The lead screw slide is I-shaped.

[0036] The second horizontal moving mechanism is disposed within the first housing, and the third driving mechanism is partially disposed within the second housing;

[0037] The first housing is further provided with a fifth through hole and a third fixing base, and the second housing is further provided with a sixth through hole;

[0038] One end of the second lead screw passes through the fifth through hole and is connected to the third transmission assembly, while the other end is connected to the third fixed base;

[0039] The third drive mechanism is connected to the third transmission assembly through the sixth through hole.

[0040] The positioning of the second horizontal moving mechanism and the third driving mechanism facilitates their disassembly.

[0041] A detection plate is provided on the first housing, and a sensing device is provided above the detection plate.

[0042] The detection plate and sensing device can be used to detect the zero point position of the water jet's rotation, providing zero point feedback functionality.

[0044] The second drive mechanism includes a second motor, a second coupling, and a third gear. The second motor is connected to the second coupling, the second coupling is connected to the third gear, and the third gear is connected to the second transmission assembly.

[0045] The first transmission assembly includes a fourth gear and a fifth gear, which are meshed together. The fourth gear is meshed with the second gear, and the fifth gear is sleeved on the connecting shaft of the first connector.

[0046] The second transmission assembly includes a sixth gear, a seventh gear, and a timing belt. The sixth gear is connected to the seventh gear via the timing belt. The sixth gear is meshed with the third gear. The seventh gear is sleeved on the connecting shaft of the first lead screw.

[0047] The third drive mechanism includes a third motor, a third coupling, and an eighth gear. The third motor is connected to the third coupling, the third coupling is connected to the eighth gear, and the eighth gear is connected to the third transmission assembly.

[0048] The third transmission component includes a ninth gear and a tenth gear, which are meshed together. The ninth gear is meshed with the eighth gear, and the tenth gear is sleeved on the connecting shaft of the second lead screw.

[0049] The medical water jet transmission device further includes a first cover plate and a second cover plate. The first cover plate is connected to the first housing. The first transmission component, the second transmission component, and the third transmission component are housed in the first cover plate. The second cover plate is connected to the second housing. The second gear, the third gear, and the eighth gear are housed in the second cover plate.

[0050] The first and second cover plates provide dust protection for the second, third, and eighth gears, the first transmission assembly, the second transmission assembly, and the third transmission assembly.

[0051] The first housing and the second housing are detachably connected.

[0052] In this embodiment, the first and second housings are detachably connected, which is beneficial for medical personnel to replace actuators such as water jets and endoscopes.

[0053] The beneficial effects of the embodiments of this application include:

[0054] The medical water jet transmission device provided in this application embodiment drives the water jet to rotate through a transmission mechanism between the first drive mechanism, the first transmission component, the first connector, and the second connector; and drives the water jet and endoscope to move in front of or behind the water jet nozzle through a transmission mechanism between the second drive mechanism, the second transmission component, and the first horizontal moving mechanism. Compared with the prior art that only contains the function of rotating the water jet, this application embodiment integrates the function of rotating the water jet and the function of driving the water jet and endoscope in front of or behind the water jet nozzle into the same device, and enables the two functions to be used simultaneously, making the medical water jet transmission device more user-friendly and better meeting the needs of medical personnel.

Detailed Implementation

[0072] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0073] In the specification of this application's embodiments, the terms "first," "second," and "third," etc., are used to distinguish different objects, rather than to describe a specific order of objects. For example, "first drive mechanism," "second drive mechanism," and "third drive mechanism" are used to distinguish different drive mechanisms, rather than to describe a specific order of drive mechanisms.

[0074] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0075] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0076] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0077] like Figure 1-13 As shown, this application embodiment provides a medical water jet transmission device 1, including:

[0078] The system comprises a first drive mechanism 10, a second drive mechanism 20, a first transmission assembly 30, a second transmission assembly 40, a first connecting member 50, a second connecting member 60, and a first horizontal moving mechanism 70, wherein...

[0079] One end of the first transmission assembly 30 is connected to the first drive mechanism 10, and the other end is connected to the first connecting member 50; one end of the second transmission assembly 40 is connected to the second drive mechanism 20, and the other end is connected to the first horizontal moving mechanism 70; the first horizontal moving mechanism 70 is connected to the water jet A1 and the endoscope B; the second connecting member 60 is sleeved on the outer side wall of the water jet A1; the first connecting member 50 is connected to the second connecting member 60;

[0080] When the first drive mechanism 10 drives the first transmission component 30 to move, the first transmission component 30 drives the first connecting member 50 to rotate, the first connecting member 50 drives the second connecting member 60 to rotate, and the second connecting member 60 drives the water jet A1 to rotate.

[0081] When the second drive mechanism 20 drives the second transmission component 40 to move, the second transmission component 40 drives the first horizontal moving mechanism 70 to move, and the first horizontal moving mechanism 70 drives the water jet A1 and the endoscope B to move in front of or behind the nozzle of the water jet A1.

[0082] It should be noted that the water jet A1 is enclosed within the return water rod A2. The front end of the return water rod A2 has a row of small holes for recovering the tissue and water cut by the water jet A1.

[0083] like Figure 7 As shown, the first drive mechanism 10 includes a first motor 11, a first coupling 12, and a second gear 13. The first motor 11 is connected to the first coupling 12, the first coupling 12 is connected to the second gear 13, and the second gear 13 is connected to the first transmission assembly 30.

[0084] like Figure 12 As shown, the second drive mechanism 20 includes a second motor 21, a second coupling 22 and a third gear 23. The second motor 21 is connected to the second coupling 22, the second coupling 22 is connected to the third gear 23, and the third gear 23 is connected to the second transmission assembly 40.

[0085] The first transmission assembly 30 includes a fourth gear 31 and a fifth gear 32, which are meshed together. The fourth gear 31 is meshed with the second gear 13, and the fifth gear 32 is sleeved on the connecting shaft of the first connecting member 50.

[0086] The second transmission assembly 40 includes a sixth gear 41, a seventh gear 42 and a timing belt 43. The sixth gear 41 is connected to the seventh gear 42 through the timing belt 43. The sixth gear 41 is meshed with the third gear 23. The seventh gear 42 is sleeved on the connecting shaft of the first lead screw 71 of the first horizontal moving mechanism 70.

[0087] The first connecting member 50 is a cylindrical spur gear C, and the second connecting member 60 is a first gear D. The cylindrical spur gear C meshes with the first gear D. This improves the smoothness and reliability of the water jet A1's rotation.

[0088] like Figure 12 As shown, the first horizontal moving mechanism 70 includes a first lead screw 71, a lead screw nut 72, and a guide member 73. The first lead screw 71 is connected to the second transmission assembly 40. The lead screw nut 72 is sleeved on the outer side wall of the first lead screw 71. The guide member 73 is connected to the lead screw nut 72. The water jet A1 and the endoscope B are respectively connected to the guide member 73. When the second transmission assembly 40 drives the first lead screw 71 to rotate, the lead screw nut 72 drives the guide member 73 to move linearly on the first lead screw 71. The guide member 73 drives the water jet A1 and the endoscope B to move in front of or behind the water jet nozzle.

[0089] The guide member 73 and the lead screw nut 72 are connected by a screw fixing connection. In other embodiments, a snap-fit ​​connection may also be used. The specific connection method can be set by those skilled in the art according to actual needs, and this document does not impose further restrictions on it.

[0090] The water jet A1 is disposed at the upper end of the guide member 73, and the endoscope B is disposed at the lower end of the guide member 73.

[0091] The structure of the first horizontal moving mechanism 70 can effectively drive the water jet A1 and the endoscope B to move together in front of or behind the nozzle of the water jet A1.

[0092] The medical water jet transmission device 1 provided in this application embodiment connects one end of the first transmission component 30 to the first drive mechanism 10 and the other end to the first connecting member 50. The first connecting member 50 is connected to the second connecting member 60, which is sleeved on the outer wall of the water jet A1. Thus, the first drive mechanism 10 can drive the first transmission component 30 to move, the first transmission component 30 drives the first connecting member 50 to rotate, the first connecting member 50 drives the second connecting member 60 to rotate, and the second connecting member 60 drives the water jet A1 to rotate. Based on this structure, this application embodiment further connects one end of the second transmission component 40 to the second drive mechanism 20 and the other end to the first horizontal moving mechanism 70. The first horizontal moving mechanism 70 is connected to the water jet A1 and the endoscope B. Thus, the second drive mechanism 20 can drive the second transmission component 40 to move, the second transmission component 40 drives the first horizontal moving mechanism 70 to move, and the first horizontal moving mechanism 70 drives the water jet A1 and the endoscope B to move in front of or behind the nozzle of the water jet A1. Therefore, the medical water jet transmission device 1 provided in this application embodiment can drive the water jet A1 and the endoscope B to move together in front of or behind the nozzle of the water jet A1 while rotating the water jet A1.

[0093] The guide member 73 is composed of a C-shaped arc structure and a cylindrical body. The water jet A1 is placed on the C-shaped arc structure, and the endoscope B is placed inside the cylindrical body.

[0094] Specifically, the water jet A1 is placed on the upper surface of the C-shaped structure. The cylinder is fixedly connected to the lower surface of the C-shaped structure.

[0095] It should also be understood that, in practical applications, a long carbon fiber tube is placed inside the cylinder, and a flexible endoscope B is connected to the end of the long carbon fiber tube.

[0096] The guide component 73 allows the endoscope B to be placed closer to the water jet A1, enabling medical personnel to directly observe the patient's lesion and the position of the water jet nozzle during surgery, thus increasing the safety of the operation.

[0097] The medical water jet transmission device 1 also includes a first housing, within which the first connecting member 50 and the first lead screw 71 are disposed. The first housing helps prevent damage to the first connecting member 50 and the first lead screw 71 from external equipment and also serves as a dustproof feature.

[0098] It should be noted that, as Figure 1 , Figure 5 and Figure 8 As shown, the first housing includes a first upper housing 80a and a first lower housing 80b. The first upper housing 80a and the first lower housing 80b can be connected by threads or by snap-fit. A first accommodating space 81 is formed inside the first lower housing 80b, and the first connecting member 50 (i.e., the cylindrical spur gear C), the first lead screw 71, and the lead screw nut 72 are disposed within the first accommodating space 81.

[0099] One end of the first housing is provided with a first through hole and a second through hole, and the other end is provided with a first fixed base 82 and a second fixed base 83; one end of the first connector 50 passes through the first through hole and is connected to the first transmission assembly 30, and the other end is connected to the first fixed base 82; one end of the first lead screw 71 passes through the second through hole and is connected to the second transmission assembly 40, and the other end is connected to the second fixed base 83.

[0100] like Figure 9 and Figure 10 As shown, a first groove 84a and a second groove 85a are provided on one side wall of the first lower housing 80b, and a first fixing base 82 and a second fixing base 83 are provided on the other side wall. A third groove 84b and a fourth groove 85b are provided on the side wall of the first upper housing 80a. The third groove 84b and the first groove 84a enclose to form the first through hole; the fourth groove 85b and the second groove 85a enclose to form the second through hole.

[0101] The first fixed base 82 is provided with a first limiting part for accommodating the connecting shaft of the cylindrical spur gear C.

[0102] The second fixed base 83 is provided with a second limiting part for accommodating the connecting shaft of the first lead screw 71.

[0103] The first through hole, the second through hole, the first fixed base 82, and the second fixed base 83 are provided to fix the positions of the cylindrical spur gear C and the first lead screw 71, preventing the cylindrical spur gear C and the first lead screw 71 from interfering with each other.

[0104] The medical water jet transmission device 1 also includes a second housing, in which the first drive mechanism 10 and the second drive mechanism 20 are partially disposed.

[0105] like Figure 1 , Figure 5 and Figure 11 As shown, the second housing includes a second upper housing 90a and a second lower housing 90b. The second upper housing 90a and the second lower housing 90b are fixedly connected by screws. A second accommodating space 91 is formed inside the second lower housing 90b, and the first driving mechanism 10 and the second driving mechanism 20 are partially disposed within the second accommodating space 91.

[0106] The second housing helps prevent damage to the first drive mechanism 10 and the second drive mechanism 20 from external equipment, and also serves as a dustproof feature.

[0107] like Figure 2 As shown, the second housing is provided with a third through hole 92 and a fourth through hole 93. The first drive mechanism 10 passes through the third through hole 92 and is connected to the first transmission assembly 30. The second drive mechanism 20 passes through the fourth through hole 93 and is connected to the second transmission assembly 40.

[0108] The third through hole 92 and the fourth through hole 93 are disposed on the side wall of the second lower housing 90b.

[0109] The third through hole 92 and the fourth through hole 93 can restrict the positions of the first drive mechanism 10 and the second drive mechanism 20, and prevent the first drive mechanism 10 and the second drive mechanism 20 from interfering with each other.

[0110] like Figure 3 As shown, the medical water jet transmission device 1 further includes a third drive mechanism 100, a third transmission component 110, and a second horizontal movement mechanism 120. One end of the third transmission component 110 is connected to the third drive mechanism 100, and the other end is connected to the second horizontal movement mechanism 120. The second horizontal movement mechanism 120 is connected to the water jet A1. When the third drive mechanism 100 drives the third transmission component 110 to move, the third transmission component 110 drives the second horizontal movement mechanism 120 to move, and the second horizontal movement mechanism 120 drives the water jet A1 to move in front of or behind the nozzle of the water jet A1.

[0111] The third drive mechanism 100 includes a third motor 101, a third coupling 102, and an eighth gear 103. The third motor 101 is connected to the third coupling 102, the third coupling 102 is connected to the eighth gear 103, and the eighth gear 103 is connected to the third transmission assembly 110.

[0112] The first motor 11, the second motor 21, and the third motor 101 are all brushless DC motors. These motors are small in size and light in weight, which can effectively reduce the size and weight of the medical water jet transmission device 1.

[0113] The third drive mechanism 100 is partially disposed within the second accommodating space 91.

[0114] The third transmission assembly 110 includes a ninth gear 111 and a tenth gear 112, which are meshed together. The ninth gear 111 is meshed with the eighth gear 103, and the tenth gear 112 is sleeved on the connecting shaft of the second lead screw 121 of the second horizontal moving mechanism 120.

[0115] The second horizontal moving mechanism 120 includes a second lead screw 121 and a lead screw slide 122. The second lead screw 121 is connected to the third transmission assembly 110, and the lead screw slide 122 is sleeved on the second lead screw 121 and connected to the water jet A1.

[0116] The second lead screw 121 and the lead screw slide 122 are disposed within the first accommodating space 81.

[0117] The arrangement of the third drive mechanism 100, the third transmission assembly 110, and the second horizontal movement mechanism 120 enables the water jet A1 to move independently in front of or behind the nozzle of the water jet A1.

[0118] The lead screw slide 122 has at least one protrusion, each of which engages with the water jet A1. The protrusions on the lead screw slide 122 reduce the contact area between the lead screw slide 122 and the water jet A1, thus preventing wear on the water jet A1.

[0119] The at least one protrusion includes a first protrusion 1221 and a second protrusion 1222. For example... Figure 13 As shown, the first protrusion 1221 and the second protrusion 1222 are disposed opposite to each other on one side wall of the lead screw slide 122. Specifically, the first protrusion 1221 is located at one end of one side wall of the lead screw slide 122, and the second protrusion 1222 is located at the other end of the side wall.

[0120] The water jet A1 is provided with a first limiting structure E and a second limiting structure F. The first protrusion 1221 is in contact with the first limiting structure E, and the second protrusion 1222 is in contact with the second limiting structure F. Therefore, the lead screw slide 122 can drive the water jet A1 to move.

[0121] The lead screw slide 122 is I-shaped.

[0122] The first housing is further provided with a fifth through hole and a third fixed base 86, and the second housing is further provided with a sixth through hole 94; one end of the second lead screw 121 passes through the fifth through hole and is connected to the third transmission assembly 110, and the other end is connected to the third fixed base 86; the third drive mechanism 100 passes through the sixth through hole 94 and is connected to the third transmission assembly 110.

[0123] The first lower housing 80b is provided with a fifth groove 87a, and the first upper housing 80a is provided with a sixth groove 87b. The fifth groove 87a and the sixth groove 87b together form the fifth through hole.

[0124] The third fixed base 86 is provided with a third limiting part for accommodating the connecting shaft of the second lead screw 121.

[0125] The first limiting part, the second limiting part and the third limiting part are all arc-shaped grooves.

[0126] The first fixing base 82, the second fixing base 83 and the third fixing base 86 are arranged sequentially on the side wall of the first lower housing 80b.

[0127] A detection plate 88 is provided on the first housing, and a sensing device 89 is provided directly above the detection plate 88. The detection plate 88 and the sensing device 89 are configured to record the number of rotations of the feedback water jet A1, so as to detect the zero point position of the rotational motion of the water jet A1 and provide a zero point feedback function.

[0128] The detection plate 88 is disposed on the side wall of the first upper housing 80a.

[0129] The sensing device 89 is a photoelectric sensor.

[0130] The medical water jet transmission device 1 further includes a first cover plate 130 and a second cover plate 140. The first cover plate 130 is connected to the first housing. The first transmission component 30, the second transmission component 40 and the third transmission component 110 are housed in the first cover plate 130. The second cover plate 140 is connected to the second housing. The second gear 13, the third gear 23 and the eighth gear 103 are housed in the second cover plate 140.

[0131] The first cover plate 130 and the second cover plate 140 can provide dust protection for the second gear 13, the third gear 23, the eighth gear 103, the first transmission assembly 30, the second transmission assembly 40 and the third transmission assembly 110.

[0132] The first housing and the second housing are detachably connected. The detachable connection can be made by screws or clips.

[0133] The arrangement of the first and second housings in this embodiment allows for a layered design of the overall structure of the medical water jet transmission device 1. Specifically, the second housing serves as the motor control layer, while the first housing is the transmission layer, facilitating disassembly and assembly by medical personnel. When medical personnel need to replace actuators such as the water jet A1 or endoscope B, only the structure of the transmission layer needs to be replaced.

[0134] A support base 95 is also provided on the outer wall of the second housing to fix the medical water knife transmission device 1 and keep it stable.

[0135] In practical applications, the medical water jet transmission device 1 has four functions, which can be implemented according to the following examples:

[0136] 1) Rotary water jet A1 function

[0137] The first drive mechanism 10 drives the first transmission component 30 to rotate, the first transmission component 30 drives the first connecting member 50 to rotate, and the first connecting member 50 drives the second connecting member 60 to rotate, so that the water jet A1 rotates together with the second connecting member 60.

[0138] 2) The function of the water jet A1 and endoscope B moving together in front of or behind the water jet nozzle.

[0139] The second drive mechanism 20 drives the second transmission assembly 40 to rotate, which in turn drives the first lead screw 71 to rotate. The lead screw nut 72 moves linearly along the first lead screw 71, causing the water jet A1 and the endoscope B to move together. The direction of their movement is either in front of or behind the water jet nozzle.

[0140] 3) The function of water jet A1 moving independently in front of or behind the water jet nozzle.

[0141] The third drive mechanism 100 drives the third transmission assembly 110 to rotate, and the third transmission assembly 110 drives the second lead screw 121 to rotate. The lead screw slide 122 moves linearly on the second lead screw 121, causing the water jet A1 to move in front of or behind the water jet nozzle.

[0142] 4) Combining the functions of points 1 and 2

[0143] This example of the function is a combination of the examples in points 1 and 2. It should be noted that, in order to achieve this function, the first drive mechanism 10 and the second drive mechanism 20 need to operate simultaneously.

[0144] The medical water jet transmission device 1 provided in this application embodiment can flexibly control the operation of a single motor or multiple motors in surgical applications (such as prostate hyperplasia lesion surgery), allowing medical personnel to make different motor control strategies according to the patient's lesion condition to achieve the purpose of eliminating lesion tissue.
