Description

Technical Field

[0001] The present application relates to interventional surgical instruments, and in particular to a balloon inflation device, as well as a surgical instrument and a surgical device having the balloon inflation device. Background Art

[0002] Currently, DSA-guided vascular interventional procedures require the surgeon to be exposed to X-rays throughout the procedure. Long-term, high-intensity radiation exposure can lead to low white blood cell counts and a weakened immune system, seriously threatening the surgeon's health. Wearing protective clothing also drains the surgeon's energy, significantly impacting surgical precision. Consequently, interventional surgical robots have gained popularity in recent years. These robots allow the surgeon to remotely control the forward, backward, and rotational movements of the guidewire catheter at the end of the robot within the operating room using a joystick on the robot's main unit, minimizing radiation exposure while improving surgical precision. Therefore, the emergence of interventional surgical robots has significant clinical value. Because balloons are inflated and deflated during interventional procedures, traditional manual inflation and deflation require rapid and forceful syringe injection, making it difficult for female surgeons or those with limited strength to achieve this.

[0003] Therefore, a balloon inflation device is needed to at least partially solve the above problems. Utility Model Content

Furthermore, for example, the term "first component" itself does not imply the existence of a "second component," nor does the term "second component" itself imply the existence of a "first component." The use of terms such as "first," "second," and "third" does not indicate any order; these terms should be interpreted as names.

[0103] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in this application are for illustrative purposes only and are not restrictive.

[0104] The present application provides a balloon inflation device, as well as a surgical instrument and a surgical device having the balloon inflation device. The surgical instrument and surgical device according to the present application are used to perform interventional surgery, preferably, to perform cardiovascular interventional surgery.

[0105] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0106] like Figure 1 and Figure 2 As shown, in a specific embodiment, the balloon inflation device 120 according to the present application includes a housing assembly 121 , an inflation syringe 124 , an inflation assembly 130 and an inflation drive assembly 140 .

[0107] The housing assembly 121 constitutes the outer shell and base of the balloon inflating device 120. The housing assembly 121 is, for example, composed of a lower housing 122 and an upper housing 123, with the upper housing 123 being used to cover the lower housing 122. The upper housing 123 is, for example, pivotally connected to the lower housing 122 on one side of the housing assembly 121. On the side of the housing assembly 121 opposite to the upper housing 123, the upper housing 123 may be provided with two hook members 123A, and the lower housing 122 may be provided with two corresponding slot members 122A. The hook members 123A and the slot members 122A may interlock, thereby forming a complete housing with the space inside being an installation space for mounting functional components.

[0108] The filling syringe 124 includes a tube portion 125, an injection port 126 and a syringe push rod 127. The injection port 126 is connected to one end of the tube portion 125, and the syringe push rod 127 is inserted into the tube portion 125 from the other end of the tube portion 125. The syringe push rod 127 is sealed with the inner wall of the tube portion 125 and is movable relative to the tube portion 125 along the axial direction DF of the tube portion 125. The axial direction DF of the tube portion 125 is also the axial direction of the filling syringe 124. The filling syringe 124 is arranged in the housing assembly 121. For example, the lower housing 122 includes a mounting seat 129 for holding the tube portion 125 of the filling syringe 124, so that the filling syringe 124 can be detachably arranged in the lower housing 122. The injection port 126 of the filling syringe 124 is exposed from the housing assembly 121 for communicating with the inner cavity of the balloon. For example, the injection port 126 protrudes from the housing assembly 121, and the end of the filling syringe 124 opposite to the injection port 126 (corresponding to the end of the syringe push rod 127) is located inside the housing assembly 121. It can be understood that the injection port 126 is sealed and connected to the inner cavity of the balloon.

[0109] The filling assembly 130 is connected to the syringe push rod 127 of the filling syringe 124 and is movable relative to the housing assembly 121 in the axial direction DF of the filling syringe 124. The filling drive assembly 140 is disposed in the housing assembly 121 and connected to the filling assembly 130, and is configured to drive the filling assembly 130 to move relative to the housing assembly 121 in the axial direction DF of the filling syringe 124. For example, the filling assembly 130 includes a retaining groove for retaining the syringe push rod 127 (e.g., a flange retaining the rear end of the syringe push rod 127). Therefore, when the filling drive assembly 140 drives the filling assembly 130 to move in the axial direction DF, the filling assembly 130 drives the syringe push rod 127 to move synchronously, thereby causing the syringe push rod 127 to extend into the tube portion 125 (advance in the axial direction DF) or withdraw from the tube portion 125 (retract in the axial direction DF) to achieve inflation or deflation of the balloon.

[0110] In order to enable the filling and piercing assembly 130 to stably move in the axial direction DF, the housing assembly 121 includes a housing guide 128 that extends in the axial direction DF of the filling and piercing syringe 124. The filling and piercing assembly 130 includes a filling and piercing guide that is connected to the housing guide 128 and is movable in the axial direction DF relative to the housing guide 128. One of the housing guide 128 and the filling and piercing guide is configured as, for example, a slide rail, and the other of the housing guide 128 and the filling and piercing guide is configured as, for example, a slide groove or a hole for accommodating the slide rail.

[0111] For example, the lower housing 122 includes a bracket 122C, and the housing guide 128 is configured as a slide rail (or guide rod) mounted on the bracket 122C. The slide rail 128 extends in the axial direction DF. The charging and punching guide is configured as a through hole, and the slide rail 128 extends through the through hole, so that the charging and punching assembly 130 can move along the slide rail 128.

[0112] The charging and piercing drive assembly 140 may include a charging and piercing driver 141 and a charging and piercing transmission mechanism 142. The charging and piercing driver 141 is configured to provide a driving force to move the charging and piercing assembly 130 relative to the housing assembly 121 in the axial direction DF of the charging and piercing syringe 124. The charging and piercing transmission mechanism 142 is connected between the charging and piercing driver 141 and the charging and piercing assembly 130 to transmit the driving force from the charging and piercing driver 141 to the charging and piercing assembly 130.

[0113] The charging and beating transmission mechanism 142 is, for example, arranged on the bracket 122C. Preferably, the charging and beating transmission mechanism 142 includes a lead screw 145 and a lead screw nut 146. The lead screw 145 is arranged on the bracket 122C of the lower shell 122. The lead screw 145 extends in the axial direction DF. The outer periphery of the lead screw 145 is provided with a lead screw thread. The lead screw nut 146 is matched with the lead screw and is sleeved on the outer periphery of the lead screw 145. At the same time, the lead screw nut is connected to the charging and beating assembly 130. The charging and beating drive member 141 is used to drive the lead screw 145 to rotate around the axis of the lead screw itself. When the lead screw 145 rotates, due to the action of the housing guide 128 and the charging and beating guide member, the charging and beating assembly 130 cannot rotate with the lead screw 145, so that the lead screw nut 146 cannot rotate with the lead screw 145 and can only move relative to the lead screw 145 along the axial direction DF, thereby causing the charging and beating assembly 130 to move along the axial direction DF.

[0114] Preferably, the charging and punching drive member 141 is configured as a motor, which works under the control of a motor driver 149. The motor 141 can rotate forward and reverse, driving the lead screw 145 to rotate forward or reverse, thereby enabling the charging and punching assembly 130 to advance or retreat along the axial direction DF.

[0115] To drive the lead screw 145 to rotate, the injection and charging transmission mechanism 142 further includes a first transmission gear 147 and a second transmission gear 148. The first transmission gear 147 is coaxially connected to the output shaft of the motor 141 for synchronous rotation therewith. The second transmission gear 148 is coaxially connected to the lead screw 145 for synchronous rotation therewith. The second transmission gear 148 meshes with the first transmission gear 147. Thus, the motor 141 drives the first transmission gear 147 to rotate, which in turn drives the second transmission gear 148 to rotate, which in turn drives the lead screw 145 to rotate, which in turn drives the lead screw 145 to rotate, which in turn drives the lead screw nut 146 to move, which in turn drives the injection and charging assembly 130 to move, which in turn drives the syringe plunger 127 to move.

[0116] Preferably, the second transmission gear 148 is arranged near the end of the lead screw 145, so as to ensure that the charging and punching assembly 130 has sufficient travel.

[0117] Of course, the motor 141 can also be connected to the lead screw 145 via a coupling. The charging and beating transmission mechanism 142 can also adopt other transmission methods such as gear and rack transmission. The charging and beating driving member 141 can also be selected from other power components such as cylinder.

[0118] Preferably, the filling and pumping assembly 130 includes a slider mechanism 131 and a force sensor 133. The slider mechanism 131 is connected to the filling and pumping drive assembly 140 (specifically, the screw nut 146) so as to move relative to the housing assembly 121 along the axial direction DF of the filling and pumping syringe 124 under the drive of the filling and pumping drive assembly 140. One end of the force sensor 133 is connected to the slider mechanism 131, and the other end is connected to the syringe push rod 127. Thus, the filling and pumping drive assembly 140 drives the slider mechanism 131 to move, the slider mechanism 131 drives the force sensor 133 to move, and the force sensor 133 drives the syringe push rod 127 to move. The force sensor 133 can sense the force applied to the syringe push rod 127, which can reflect the air pressure in the balloon. For example, when the filling and pumping drive assembly 140 drives the filling and pumping assembly 130 to drive the syringe push rod 127 into the tube portion 125, the balloon is inflated, the air pressure therein increases, and the positive pressure sensed by the force sensor 133 increases. The filling and pumping drive assembly 140 needs to output a greater driving force to continue to push the syringe push rod 127 forward. When the filling and pumping drive assembly 140 drives the filling and pumping assembly 130 to withdraw the syringe push rod 127 from the tube portion 125, the balloon is deflated, the air pressure therein decreases, and the negative pressure sensed by the force sensor 133 increases. The filling and pumping drive assembly 140 needs to output a greater driving force to continue to withdraw the syringe push rod 127. Therefore, the balloon filling and pumping device 120 can determine the balloon filling state based on the measurement value of the force sensor 133 and control the operation of the filling and pumping drive 141.

[0119] Specifically, the slider mechanism 131 includes, for example, a first slider 132 and a second slider 134, the first slider 132 being connected to the second slider 134. A force sensor 133 is connected to the first slider 132, and a lead screw nut 146 is embedded in the second slider 134. The filling assembly 130 also includes a connector 135, one end of which, along the axial direction DF, is connected to the force sensor 133, and the other end is connected to the syringe plunger 127, thereby connecting the force sensor 133 to the syringe plunger 127. A retaining groove for retaining the rear flange of the syringe plunger 127 is provided on the connector 135. The connector 135 does not contact the slider mechanism 131.

[0120] It can be understood that the first slider 132 and the second slider 134 are both provided with channels for leading out the cables of the force sensor 133 .

[0121] Preferably, the balloon inflating device 120 further includes two position sensors 151. These two position sensors 151 are, for example, disposed on the bracket 122C and spaced apart along the axial direction DF, and are configured to sense the position of the inflating assembly 130. Specifically, when the inflating assembly 130 advances or retreats along the axial direction DF to a safe limit position, the inflating assembly 130 triggers the two position sensors 151, respectively, thereby enabling the balloon inflating device 120 to deactivate the inflating drive assembly 140 and prevent further movement of the inflating assembly 130, which could lead to safety issues. The position sensors 151 can be configured, for example, as photoelectric sensors, micro switches, proximity switches, and the like.

[0122] The balloon inflating device 120 is intended to be positioned at the front end of a surgical device, for example, in an operating room. To protect the surgeon from radiation exposure, the balloon inflating device 120 is further configured such that the inflating drive assembly 140 is coupled to a back-end control device of the surgical device (e.g., a control device in a control room), allowing the surgeon to remotely control the inflating drive assembly 140. The inflating drive assembly 140 can be connected to the back-end control device either wired or wirelessly.

[0123] In the illustrated embodiment, the inflation and filling drive assembly 140 is connected to the backend control device via a wired connection. For example, an aviation plug 157 is provided in the installation space, and the cable of the motor driver 149 is connected to the backend control device via a cable plugged into the aviation plug. Similarly, the cables of the force sensor 133 and position sensor 151 are both connected to the backend control device via cables plugged into the aviation plug. This allows the backend control device to control the operation of the balloon inflation and filling device 120.

[0124] Preferably, the balloon inflation device 120 further includes a forward button 158 and / or a reverse button 159. The forward button 158 is disposed on the housing assembly 121 and electrically connected to the inflation drive assembly 140, and is used to activate the inflation drive assembly 140, causing the inflation drive assembly 140 to push the syringe push rod 127 into the tubing 125 of the inflation syringe 124. For example, the forward button 158 is disposed on the lower housing 122. When a user presses the forward button 158, the inflation drive assembly 140 receives a command to advance the inflation drive assembly 130 in the axial direction DF. The reverse button 159 is also disposed on the housing assembly and electrically connected to the inflation drive assembly 140, and is used to activate the inflation drive assembly 140, causing the inflation drive assembly 130 to withdraw the syringe push rod 127 from the tubing 125. For example, the back button 159 is provided on the lower housing 122 . When the user presses the back button 159 , the charging and punching driving assembly 140 receives a command to cause the charging and punching assembly 130 to retreat along the axial direction DF.

[0125] During actual surgery, balloons vary in size, requiring the inflation and insufflation assembly 130 to determine its stroke based on the balloon's volume. Larger balloons require a longer stroke, while smaller balloons require a shorter stroke. Therefore, the initial position of the inflation and insufflation assembly 130 is not fixed and must be adjusted based on the balloon's size. The forward button 158 and / or reverse button 159 allow the user to manually adjust the initial position of the inflation and insufflation assembly 130 before surgery.

[0126] Before surgery, the user opens the upper housing 123, adjusts the initial position of the inflation assembly 130, sets up the inflation syringe 124, connects the balloon to the injection port 126, and then closes the upper housing 123, completing the preparations. Preferably, when the upper housing 123 covers the lower housing 122, the forward button 158 and / or the reverse button 159 are covered by the upper housing 123, thereby preventing accidental operation of the forward button 158 and / or the reverse button 159. During surgery, the user can control the balloon inflation device 120 via the back-end control device.

[0127] The balloon inflating device 120 is used in conjunction with a surgical robot, wherein the bottom plate 122B of the lower housing 122 is used for mounting to the surgical robot. The bracket 122C, the motor driver 149 and the aviation plug 157 can all be disposed on the bottom plate 122B.

[0128] In a specific embodiment, the surgical instrument for performing an interventional procedure according to the present application includes a balloon and the aforementioned balloon inflation device 120. The balloon is placed within the human body (e.g., within a blood vessel), and an injection port 126 of an inflation syringe 124 is in sealed communication with the inner lumen of the balloon. Thus, the user can inflate or deflate the balloon using the balloon inflation device 120.

[0129] In a specific embodiment, a surgical device for performing an interventional procedure according to the present application includes a surgical instrument and a backend control device according to the present application.
