[0050] Overall structure
[0051] The following combination Figure 1 , Figure 2 The overall structure of the surgical energy instrument of the present application is described. Figure 1 This is an assembly view of a surgical energy device. Figure 2 is an axial cross-sectional view of a surgical energy instrument.
[0052] See also Figure 1 , Figure 2 The surgical energy device of the present application includes a housing 100, an execution unit 1, and a shielding unit 2. In a common example, the execution unit 1 is in a longitudinal shape, with a distal end for inserting into a subject and a proximal end close to the operator. The execution unit 1 is arranged in a manner of passing through the housing 100, and an energy pipeline, such as a jet pipeline, a hot steam pipeline, etc., is arranged inside the execution unit 1, and an emission hole 11 is arranged near the distal end thereof.
[0053] For the sake of convenience, the plugging and unplugging direction of the actuator 1, i.e., the longitudinal direction, is taken as the axial direction, the direction perpendicular to the axial direction is taken as the radial direction, and the side of the distal end is taken as the front side and the side of the proximal end is taken as the rear side in the axial direction. Preferably, the direction of the emission hole 11 intersects the axial direction, for example, the emission hole 11 can be set to open radially so that the center line of the energy beam ejected from it is perpendicular to the axial direction.
[0054] During the usual ablation / resection process, the water jet or laser, steam or other energy beam generated by the external energy source enters the energy pipeline in the execution unit 1 from the external pipeline 3, and then is ejected from the emission hole 11 to perform ablation on the lesion tissue. The external pipeline 3 and the energy pipeline in the execution unit 1 constitute a transmission channel for the energy beam.
[0055] When the operation is completed or an emergency requires emergency stop, the usual practice is to cut off the energy source, such as stopping the motor. However, after the energy source is cut off, the residual energy beam in the transmission channel can still cause damage to human tissue in a short period of time. For example, after the booster pumping system of a high-pressure water jet surgical energy device stops working, it takes several seconds for the jet energy of the emission hole 11 to be reduced to a level that will not damage human tissue.
[0056] To this end, the present application provides a shielding unit 2 for quickly shielding the emission hole 11 when necessary to prevent the energy beam in the transmission channel from damaging human tissue.
[0057] Occlusion Unit
[0058] Continue to view Figure 1The shielding unit 2 includes a shielding portion 21 for shielding the emitting hole 11. As a preferred embodiment, the shielding portion 21 is a sleeve sleeved on the execution unit 1. In this way, during the rotation of the execution unit 1, no matter which direction the emitting hole 11 faces, it can be shielded by the shielding portion 21 as a sleeve.
[0059] When the shielding unit 2 is in the working state, the shielding portion 21 moves forward to a shielding position that shields the emission hole 11, thereby preventing the energy beam in the transmission channel from being ejected and damaging human tissue. When the shielding unit 2 is in the non-working state, the external energy source is input normally, and the shielding portion 21 moves backward to a avoidance position that does not shield the emission hole 11, thereby ensuring that the emission hole 11 ejects the energy beam normally. In other words, the shielding portion 21 switches back and forth between the shielding position and the avoidance position through axial telescopic movement, thereby controlling whether the energy beam is ejected or not.
[0060] The shielding unit 2 further includes a driving part 22 near the proximal end, that is, the driving part 22 is arranged further back than the shielding part 21. When the shielding unit 2 is not in operation, the driving part 22 drives the shielding part 21 to move backward to the avoidance position.
[0061] As a preferred method, an elastic member 23 is connected between the shielding parts 21, and the elastic member 23 has a specified deformation allowance in the axial direction, such as a spring. When the driving part 22 drives the shielding part 21 to move backward to the avoidance position, the elastic member 23 undergoes elastic deformation and accumulates force; after the driving part 22 stops working, the elastic member 23 rebounds and drives the shielding part 21 to return forward to the shielding position.
[0062] It can be understood that the elastic member 23 can be connected between the driving portion 22 and the shielding portion 21, and can also be connected between the shielding portion 21 and the shell 100. When connected between the driving portion 22 and the shielding portion 21, the elastic member 23 is compressed and stores force in the process of the driving portion 22 driving the shielding portion 21 to move backward to the avoidance position. When connected between the shielding portion 21 and the shell 100, the elastic member 23 can be arranged between the rear end of the shielding portion 21 and the front side of the shell 100. At this time, the elastic member 23 is stretched and stores force in the process of the driving portion 22 driving the shielding portion 21 to move backward to the avoidance position. The principles of the two methods are the same and will not be elaborated in detail.
[0063] Thus, the driving part 22 and the external energy source can be connected to the same operating part, for example, the driving part 22 can be connected to the emergency stop button or foot switch of the medical device. When the emergency stop button is pressed or the foot switch is released, the external energy source is cut off, and the driving part 22 stops working at the same time, and the elastic member 23 quickly drives the shielding part 21 to rebound and reset, which can minimize the damage of residual energy.
[0064] Exemplarily, the shielding portion 21 is disposed through the shell 100 , while the elastic member 23 and the driving portion 22 are located in the accommodating cavity inside the shell 100 to avoid contamination by body fluids during operation and to facilitate maintenance and replacement.
[0065] In one embodiment, an axially extending transmission shaft 24 is connected between the driving part 22 and the shielding part 21, the elastic member 23 is sleeved on the transmission shaft 24, and the driving part 22 is a motor. The front end of the transmission shaft 24 is fixedly connected to the rear end of the shielding part 21, and the transmission shaft 24 can move axially.
[0066] When the shielding unit 2 is not in operation, the external energy source is normally input, the driving part 22 drives the transmission shaft 24 to retreat, and the transmission shaft 24 drives the shielding part 21 to move backward to the avoidance position, at which time the elastic member 23 undergoes elastic deformation and accumulates force. After the driving part 22 stops working, the elastic member 23 drives the transmission shaft 24 and the shielding part 21 to move forward quickly and reset to the shielding position to prevent the residual energy in the transmission channel from being ejected.
[0067] In another embodiment, the shielding unit 2 is in the form of an electromagnet. The driving part 22 and the shielding part 21 are respectively provided with a first electromagnetic module and a second electromagnetic module (not shown in the figure), and the elastic member 23 can be arranged between the first electromagnetic module and the second electromagnetic module, or between the second electromagnetic module and the housing 100 on the front side.
[0068] When the shielding unit 2 is not in operation, the external energy source is normally input, the driving unit 22 is powered on and the second electromagnetic module drives the shielding unit 21 to move toward the first electromagnetic module, thereby causing the shielding unit 21 to move backward to the avoidance position, and the elastic member 23 undergoes elastic deformation to store force. When the driving unit 22 is powered off, the elastic member 23 drives the second electromagnetic module and the shielding unit 21 to move forward quickly and reset to the shielding position to prevent the residual energy in the transmission channel from being ejected.
[0069] Slide box
[0070] Continue to view Figure 1 , Figure 2 As a preferred embodiment, the execution unit 1, the shielding portion, and the driving portion are all connected to the slide box 4 and can move reciprocally along the axial direction with the slide box 4.
[0071] Specifically, the slide box 4 is sleeved on the translation drive shaft 41 and the rotation drive shaft 42. A transmission assembly is arranged inside the slide box 4, which can drive the execution unit 1 to rotate around the axial direction under the drive of the rotation drive shaft 42 to adjust the direction of the jet ejected from the launch hole 11. The slide box 4 can also drive the execution unit 1 and the shielding unit 2 to move forward and backward along the axial direction under the drive of the translation drive shaft 41 to adjust the depth of the execution unit 1.
[0072] It can be understood that for a medical device that is hand-held and operated by a doctor, the transmission shaft 24, the slide box 4, the translation drive shaft 41, and the rotation drive shaft 42 can be omitted, and the drive unit 22 can be simplified to a mechanical button on the handle. When it is necessary to spray energy, the button is pressed to trigger the shielding unit 21 and move it to the avoidance position, and the emission hole 11 is opened. When it is necessary to stop, the button is released, and the shielding unit 21 is reset to the shielding position under the drive of the elastic member 23.
[0073] In summary, the surgical energy device of the present application is provided with a shielding portion 21 capable of shielding the emission hole 11, and the shielding portion 21 is switched between the shielding position and the avoidance position through the axial telescopic movement, so that the jet ejected from the emission hole 11 will not be interfered with during the ablation operation, and the emission hole 11 can be quickly shielded when the external energy source is cut off, so as to avoid the residual energy from damaging human tissue. For medical devices such as lasers and electric knives, although the risk of harming human tissue can be immediately eliminated after the energy source is cut off, the use of the solution of the present application is equivalent to adding a first-level protection measure, which can reduce the risk of misoperation or failure of the machine's control system.
[0074] It is understandable that during the ablation operation, the shielding part 21 needs to be moved to the avoidance position. However, when the shielding part 21 moves to the shielding position, the external energy source can be in a cut-off state, or it can continue to input the energy beam into the energy pipeline in the execution unit 1. The energy beam will be blocked by the shielding part 21 at the emission hole 11, and the water jet / steam jet can also flow out from the front side gap between the shielding part 21 and the execution unit 1. In this way, the ablation operation can be terminated to avoid damage to human tissue, and the external energy source equipment can be kept from shutting down, so as to quickly switch to the state of the ablation operation again, thereby reducing the trouble of frequently starting and stopping the energy source equipment between two ablation operations with a short interval.
[0075] It should be understood that the specific embodiments described above are only used to explain the present application, and the protection scope of the present application is not limited thereto. Any technical personnel familiar with the technical field can make changes, substitutions, and combinations within the technical scope disclosed in the present application according to the technical solution and concept of the present application, which should be covered by the protection scope of the present application.
