Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anchor conveyor and a conveying system. Background Art

[0002] The prostate is a gland in the male reproductive system, connected to the bladder and urethra, with a sphincter below. The normal size of the prostate is about 20 ml, the size of a walnut. However, under the influence of various factors, the prostate will proliferate and hypertrophy, exerting pressure on the urethra, causing urination difficulties, and then damaging bladder function, resulting in symptoms such as urination difficulties, frequent urination, and hematuria, that is, a variety of common geriatric diseases.

[0003] The main treatment methods currently include drug therapy, laser resection, permanent stent expansion, disposable expander and other technologies, and prostate suspension. Prostate suspension generally requires the use of a delivery system, which is first inserted into the prostate segment of the urethra to compress the prostate, and then the anchor with PE (polyethylene) wire is delivered to the outside of the prostate, and then a fixator is installed on the inside and the PE wire is cut. After the delivery system is withdrawn, the prostate cannot fully rebound because it is constrained by the anchor to achieve the purpose of expanding the urethra.

[0004] The existing delivery system generally adopts a one-gun-one-nail model. Each patient needs to use 4 to 6 anchors during surgery, and a new delivery system needs to be replaced for each anchor, resulting in high costs. In addition, the delivery system needs to cooperate with the cystoscope during surgery. In the prior art, the cystoscope needs to be reinstalled every time the delivery system is replaced, resulting in a relatively long operation time. The internal power spring in the existing delivery system is pre-tightened, but during the window period of up to 3 to 5 years, the power spring will gradually fatigue and fail, making it impossible to determine the actual thrust or pull.

The same reference numerals in the figures represent the same or similar structures, and thus their repeated descriptions will be omitted. "Or" and "or" in the specification may both mean "and" or "or". Although the terms "upper", "lower", "between", etc. may be used in this specification to describe different exemplary features and elements of the present invention, these terms are used herein only for convenience, such as according to the directions of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present invention. Although "first" or "second" etc. are used in this specification to represent certain features, they are only used to represent the function, and are not used as a limitation on the number and importance of specific features. In the present invention, the distal end and the proximal end are relative to the operator, the end closer to the operator is the proximal end, and the end farther from the operator, that is, the end closer to the surgical site is the distal end. For example, in Figure 1 In the perspective of , for the puncture needle 3, its proximal end is the left end and its distal end is the right end.

[0049] The present invention provides an anchor conveyor and an anchor conveying system including the anchor conveyor. The anchor conveyor includes a handle housing and at least partially located inside the handle housing: a first actuator and a second actuator, when the first actuator moves along the first direction, it drives the second actuator to move along the second direction; a power assembly, which can be switched between a power storage state and a power release state, when the power assembly is in the power storage state and the second actuator moves along the second direction, the power assembly releases power to the second actuator and enters the power release state; and a reset assembly, which gives the second actuator a biasing force along a third direction, and the third direction is opposite to the second direction. The anchor conveying system is used to convey anchors, and the system includes a puncture needle and the above-mentioned anchor conveyor, the anchor at least partially enters the inner cavity of the puncture needle, and the proximal end of the puncture needle is detachably connected to the second actuator. After one delivery, the conveyor of the present invention can reset the second actuator through the reset component, and the power component can return to the power storage state to prepare for the next delivery, thereby realizing the reuse of the conveyor and reducing the cost and time of surgery.

[0050] Refer to the following Figures 1 to 3 , the structure of the anchor conveyor and the conveying system is described in detail in conjunction with an embodiment of the present invention. In this embodiment, the anchor conveyor and the conveying system are used for prostate anchor delivery as an example for explanation. It can be understood that the present invention can also be applied to other types of anchor delivery, such as the delivery of anchors for treating tissue hypertrophy, sagging, stenosis, etc. in other locations, or the delivery of anchors for suspending the face or exposed organs for cosmetic purposes. The anchor conveyor and the conveying system can be applied to the human body, and can also be applied to animals, human models or animal models, etc.

[0051] like Figure 1 As shown, in this embodiment, the anchor conveyor includes a handle 1, an insertion section 2 and a wrench 4. The anchor conveying system includes the conveyor and the puncture needle 3. The handle 1 is provided with a second actuator for driving the puncture needle 3 to move in the distal direction, and is provided with a power assembly for providing power to the second actuator. The insertion section 2 is the part inserted into the urethra, and includes three parts: a main tube for fixing the cystoscope 5, a guide tube for the puncture needle 3, and a tangent guide groove. The puncture needle 3 is used to puncture the prostate and establish a delivery channel for the anchor. The anchor is at least partially arranged in the internal cavity of the puncture needle 3. The proximal end of the puncture needle 3 is detachably mounted on the second actuator of the handle 1, and the puncture needle 3 is at least partially inserted into the insertion section 2.

[0052] like Figure 1 and Figure 2As shown, the handle 11 includes a handle housing 11 and a first actuator, a second actuator, a power assembly and a reset assembly at least partially located inside the handle housing 11. The handle housing 11 includes a receiving portion 111 located at the top and a gripping portion 112 located at the bottom. The receiving portion 111 has a large internal space to accommodate the main components of the handle 1, and the gripping portion 112 is formed in a shape that is convenient for the operator to hold. The proximal end portion of the insertion section 2 at least partially enters the interior of the handle housing 11.

[0053] like Figure 2 As shown in FIG. 1 , the first actuating member is a puncture trigger 12 disposed at the connection portion between the grip portion 112 and the accommodating portion 111, and the puncture trigger 12 is at least partially exposed outside the handle housing 11. When the operator presses the puncture trigger 12, the puncture trigger 12 moves along a first direction. Figure 2 The first direction is a horizontal direction from right to left in the perspective of the handle housing 11. The second actuator is a push rod 14, which is rotatably connected to the handle housing 11 via a rotation axis 143, and the push rod 14 includes a first section 141 and a second section 142 located on both sides of the rotation axis 143. The first section 141 of the push rod 14 is at least partially exposed to the outside of the handle housing 11, and a slot connected to the proximal end of the puncture needle 3 is provided at the top of the first section 141. Figure 3 As shown, the proximal end of the puncture needle 3 can be detachably connected to the slot of the push rod 14. Therefore, the puncture needle 3 is exposed outside the handle housing 11, which is convenient for the operator to observe the position of the puncture needle 3 and increases the convenience of the operation.

[0054] like Figure 2 As shown, a main brake 131 is also provided inside the handle housing 11, and the main brake 131 includes an arc segment and a straight segment. The puncture trigger 12 is connected to the second segment 142 of the push rod 14 through the arc segment and the straight segment in sequence, and the straight segment is parallel to the first direction. The arc segment is connected to a first biasing member. In this embodiment, the first biasing member is a trigger spring 132, and can be optionally a tension spring, one end of which is fixed to the handle housing 11, and the other end is fixed to the arc segment, and the arc segment is a circular arc structure protruding outward relative to the trigger spring 132. When the puncture trigger 12 is pressed and moves along the first direction, the push rod 14 rotates along the second direction. Figure 2, the second direction is the clockwise direction. As a result, the first section 141 of the push rod 14 moves in the distal direction, driving the puncture needle 3 to move in the distal direction, and at the same time, the power assembly provides power to the first section 141 of the push rod 14 to move in the distal direction, thereby achieving the puncture effect. In this process, the trigger spring 132 undergoes elastic stretching deformation under the action of the arc segment. At this time, if the puncture trigger 12 is released, under the action of the trigger spring 132, the puncture trigger 12 is reset from left to right, and the puncture trigger 12 and the main brake 131 can return to the initial state. In other alternative embodiments, the first biasing member can also adopt an elastic structure such as a compression spring, a torsion spring, a spring sheet, an elastic pad, etc.

[0055] like Figure 2 As shown, the reset assembly includes a reset spring 151 and a reset wire 152, the first end of the reset spring 151 is fixed to the handle housing 11, and the second end of the reset spring 151 is connected to the first section 141 of the push rod 14 through the reset wire 152. The reset wire 152 can be formed by weaving polymer or metal cables, the first end (the lower end) is hung on the mounting column of the handle housing 11, the second end (the upper end) is fixed to the top of the first section 141 of the push rod 14, and the middle passes through the circular hole of the reset spring 151 to form a movable pulley structure. The reset spring 151 can be a tension spring. Therefore, the present invention sets the reset assembly. When the first section 141 of the push rod 14 rotates in the clockwise direction to push the puncture needle 3 to move in the distal direction, the reset spring 151 undergoes elastic deformation. If the force in the second direction applied to the push rod 14 is less than the elastic deformation restoring force of the reset spring 151, the push rod 14 can rotate in the third direction under the action of the reset spring 151 and return to its initial state. The third direction is opposite to the second direction. Figure 2 , the third direction is counterclockwise. In another alternative embodiment, the reset wire 152 can be arranged on the right side of the push rod 14, the second end of the reset wire 152 is fixed to the second section 142 of the push rod 14, and the first end of the reset wire 152 is hung on the mounting column of the handle housing 11, and the first end of the reset wire 152 is located above the second end. In yet another alternative embodiment, the reset assembly may also include a reset compression spring, which is arranged between the right side of the first section 141 of the push rod 14 and the handle housing 11, or between the left side of the second section 142 of the push rod 14 and the handle housing 11. In yet another alternative embodiment, the reset assembly may also include an elastic sheet, an elastic pad or other elastic structure.

[0056] like Figure 2As shown, in this embodiment, the power assembly can switch between a power storage state and a power release state. In this embodiment, the power assembly includes a power spring 161, a power cable 162 and a main winding wheel 163. The first end of the power spring 161 is fixed to the handle housing 11, and the second end of the power spring 161 is connected to the first end of the power cable 162. The power cable 162 can be formed by weaving a polymer or a metal cable, and the second end of the power cable 162 is connected to the main winding wheel 163, and the middle part of the power cable 162 passes through the rotating shaft 143 of the push rod 14 to form a movable pulley structure. The main winding wheel 163 is rotatably fixed to the handle housing 11. The power spring 161 can be optionally a tension spring. When the main winding wheel 163 rotates in the fourth direction, the power pull wire 162 can be driven to move. The second end of the power pull wire 162 is wound around the main winding wheel 163 for more turns, that is, the main winding wheel 163 is wound up, and the first end of the power pull wire 162 pulls the second end of the power spring 161 to move in a direction away from the first end, that is, the power spring 161 is stretched, so that the power spring 161 is pre-tightened and elastically deformed. At this time, the power assembly is in a power storage state. When the operator presses the puncture trigger 12 to rotate the push rod 14 in the second direction, the elastic deformation recovery force of the power spring 161 provides power for the movement of the push rod 14, that is, its pre-tightening force is released as power to the push rod 14, thereby increasing the driving force and driving speed of the push rod 14 on the puncture needle 3, so that the puncture needle 3 can smoothly pierce the prostate. At this time, the length of the power spring 161 is shortened, and the power assembly is in a force release state. Therefore, in this embodiment, the preload force of the power spring 161 can be adjusted by the main winding wheel 163. And after the power spring 161 enters the release state, the main winding wheel 163 can be adjusted to make the power assembly enter the storage state, so as to prepare for the next use of the conveyor.

[0057] Furthermore, in this embodiment, in order to facilitate the use of the operator, a first opening is provided at a position where the handle housing 11 is opposite to the main winding wheel 163, and a first adjustment fitting portion is provided on a side of the main winding wheel 163 facing the first opening. The main winding wheel 163 can be adjusted directly outside the handle housing 11 by cooperating with a wrench 4 and the first adjustment fitting portion to achieve pre-tightening of the power spring 161. Figure 1 and Figure 3As shown, in this embodiment, the first adjustment matching portion is a hexagonal hole, and the wrench 4 includes a driving portion 41 and an operating portion 42. The front end of the driving portion 41 can be embedded in the inner hexagonal hole, and the power spring 161 can be pre-tightened by rotating the operating portion 42. In other embodiments, the first adjustment matching portion can also be a groove or hole of other shapes, or the first adjustment matching portion is a prism protruding from the surface of the handle housing 11, and the front end of the driving portion 41 of the wrench 4 is provided with a matching groove.

[0058] like Figure 2 As shown, the handle 1 also includes a retraction switch. In this embodiment, the retraction switch is a retraction trigger 181. The retraction trigger 181 is partially located inside the handle housing 11, and partially protrudes outside the handle housing 11, so that the operator can operate outside the handle housing 11. The retraction trigger 181 is provided with a protrusion on the side facing the main winding wheel 163. When the retraction trigger 181 is not subjected to the actuation force of the operator, the protrusion blocks the main winding wheel 163 from rotating. When the main winding wheel 163 is rotated in the fourth direction by the wrench 4, the force applied by the operator to the main winding wheel 163 by the wrench 4 overcomes the blocking force of the retraction trigger 181, so that the main winding wheel 163 can rotate in the fourth direction to preload the power spring 161. After the puncture needle 3 is pushed out in the distal direction, an external force (e.g., pressing the retraction trigger 181 downward) can be applied to separate the raised portion of the retraction trigger 181 from the main winding wheel 163, and the main winding wheel 163 rotates in the fifth direction (opposite to the fourth direction) under the action of the power pull wire 162, and the number of turns of the power pull wire 162 on the main winding wheel 163 is reduced, that is, the main winding wheel 163 releases the wire, and the power pull wire 162 no longer pulls the push rod 14 in the second direction. Under the action of the reset spring 151, the push rod 14 can be reset to its initial state along the third direction.

[0059] like Figure 2As shown, the handle 1 is at least partially located in the handle housing 11 of the wire cutting assembly, and the wire cutting assembly includes an auxiliary brake 171, a wire cutting switch, a cutter 173, a wire cutting spring (not shown in the figure), a wire cutting pull line and an auxiliary winding wheel 174. In this embodiment, when the auxiliary brake 171 moves to the right, it can drive the cutter 173 to move to the right and extend out of the handle housing 11 to cut the redundant pull line of the anchor. The wire cutting switch is a wire cutting trigger 172. The wire cutting trigger 172 is partially located inside the handle housing 11 and partially located outside the handle housing 11 for the convenience of the operator. When the wire cutting trigger 172 is not actuated, it blocks the auxiliary brake 171 from moving to the right, ensuring that the cutter 173 does not extend out of the handle housing 11. When the wire cutting trigger 172 is actuated by the operator (for example, the wire cutting trigger 172 is lifted upward), it can be separated from the auxiliary brake 171, and the cutter 173 can move to the right. The tangent spring gives the cutter 173 a biasing force toward the outside of the handle housing 11, thereby providing power for the extension of the cutter 173. The tangent spring is connected to the secondary winding wheel 174 through the tangent pull line, and the secondary winding wheel 174 is rotatably fixed to the handle housing 11. The tangent spring can be pre-tightened by adjusting the secondary winding wheel 174. Furthermore, in order to facilitate the operator to pre-tighten the tangent spring outside the handle housing 11, a second opening is provided at a position opposite to the handle housing 11 and the secondary winding wheel 174, and a second adjustment fitting portion is provided on the side of the secondary winding wheel 174 facing the second opening. In this embodiment, the second adjustment fitting portion is a hexagonal socket, and the front end of the driving portion 41 of the wrench 4 can be embedded in the interior of the hexagonal socket, and the tangent spring can be pre-tightened by rotating the operating portion 42. In other embodiments, the second adjustment matching portion may also be a groove of other shapes, or the second adjustment matching portion may be a prism protruding from the surface of the handle housing 11, and a matching groove is provided at the front end of the driving portion 41 of the wrench 4. Therefore, after the tangent assembly is used once, the tangent spring can be pre-tightened again by the wrench 4 for the next use.

[0060] like Figure 2 As shown, the handle 1 also includes a second biasing member. In this embodiment, the second biasing member is a switch spring 182, which can be optionally a tension spring, and its two ends are respectively connected to the retraction switch and the thread trimming trigger 172. When the retraction trigger 181 is pressed down or the thread trimming trigger 172 is lifted up, the switch spring 182 will be stretched and deformed. After the retraction trigger 181 or the thread trimming trigger 172 is released, the switch spring 182 pulls it back to the initial state.

[0061] Combine the following Figures 1 to 3The structure of the anchor delivery system is shown, and the working principle of the delivery device and the delivery system is specifically introduced. During the operation, the following operations are mainly performed.

[0062] (1) First, insert the puncture needle 3 into Figure 3 As shown, the puncture needle 3 is inserted into the internal cavity of the insertion end, and then the proximal end of the puncture needle 3 is inserted into the top groove of the first section 141 of the push rod 14 to complete the installation of the puncture needle 3.

[0063] (2) Then, the wrench 4 is used to adjust the main winding wheel 163 and the secondary winding wheel 174 respectively, so as to pre-tighten the power spring 161 and the tangent spring, and both the power spring 161 and the tangent spring undergo elastic deformation.

[0064] (3) Insert the insertion section 2 into the urethra through the sheath to reach the prostate segment. Use the cystoscope 5 to observe and find the puncture position.

[0065] (4) Puncture stage: the puncture trigger 12 is pressed, and the puncture trigger 12 moves in the first direction, and the main brake 131 pushes the push rod 14 to rotate in the second direction, the trigger spring 132 is elastically deformed, and the return spring 151 is elastically deformed. The elastic deformation recovery force of the power spring 161 provides power for the movement of the push rod 14, and the first section 141 of the push rod 14 pushes the puncture needle 3 to puncture the entire prostate. The radius of the prostate with a volume of 80 ml is generally 3 cm. To ensure that the prostate outer membrane is punctured, the stroke of the puncture needle 3 is set to 3.5 cm.

[0066] (5) Then the anchor is pushed out of the inner cavity of the puncture needle 3 by manual wire feeding to reach the position of the prostate adventitia.

[0067] (6) Press the retraction trigger 181, the main winding wheel 163 rotates in the fifth direction to release the line, the reset spring 151 resets the push rod 14 with the puncture needle 3, and then manually pull the pull line at the tail of the anchor to ensure that it is closely attached to the prostate membrane.

[0068] (7) Press the wire cutting trigger 172, and the cutter 173 pops out of the handle housing 11 to cut off the excess wire of the anchor.

[0069] (8) Finally, withdraw the entire insertion end from the urethra to complete one-point prostate restriction.

[0070] Patients with benign prostatic hyperplasia need at least four positions of restraint to achieve the purpose of opening the urethra. When the conveyor and the conveying system are used for the next operation, since the push rod 14 and the puncture trigger 12 have been reset to the initial state, and the power spring 161 and the tangent spring can be pre-tightened again by using the wrench 4, the conveyor and the conveying system can be reused, and the pre-tightening force is adjustable.

[0071] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
