Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present utility model, the present utility model is described in detail below with reference to the accompanying drawings and detailed description.

Embodiments of the present utility model provide a clasp assembly forceps as an auxiliary assembly tool for a hip joint prosthesis for clamping a clasp 210 to insert the clasp 210 into a ball cup 220 or to remove the clasp 210 from the ball cup 220.

Referring to fig. 1 to 3, the clasp assembling pliers according to the embodiment of the present utility model includes two pliers bodies 100, the pliers bodies 100 including a jaw 120, a jaw 110 provided at one end of the jaw 120, and a jaw handle 130 provided at the other end of the jaw 120. The middle parts of the two clamp bars 120 are hinged with each other, and the two clamp heads 110 extend in parallel. Alternatively, the middle portions of the two clamp bars 120 may be hinged to each other by means of pins, pins or screws. The two binding clip 110 may extend in parallel along the direction of the line of extension of the binding clip 120, or may be disposed at a non-zero angle to the binding clip 120. For example, the binding clip 110 may be bent to one side of the binding clip 120.

The clamp head 110 includes a base 111 and a reinforcing portion 112 protruding from an outer circumferential surface of the base 111, the reinforcing portion 112 extending in a longitudinal direction of the base 111. The base 111 serves as a main structure of the binding clip 110, and the reinforcing portion 112 serves as a reinforcing structure based on the base 111, and the reinforcing portion 112 serves to mainly reinforce the structural strength of the binding clip 110 in one or more directions perpendicular to the longitudinal direction of the base 111.

Alternatively, the reinforcement portion 112 may extend along a straight line in the longitudinal direction of the base 111 or may extend along a curved line, as long as it has a certain length in the longitudinal direction of the base 111, so that the structural strength of the clamp head 110 can be improved from a structural point of view. Alternatively, the reinforcing portion 112 may penetrate to both ends of the base 111, or may be provided in a partial region in the longitudinal direction of the base 111.

Alternatively, the base 111 and the reinforcing portion 112 may be formed in a single piece or may be formed in a separate piece. For example, the clamp body 100 may be made of a metal material, and the base 111 and the reinforcement portion 112 of the clamp head 110 may be formed by machining the metal material by cutting or tapping. Of course, the pliers body 100 is not limited to metal materials, and other materials with high structural strength, such as organic synthetic materials, may be used.

The clamp ring assembly pliers of the embodiment of the utility model have the advantages that the pliers head 110 not only comprises the base body 111, but also comprises the reinforcing part 112 protruding on the outer peripheral surface of the base body 111 along the length direction of the base body 111, and the reinforcing part 112 can strengthen the structural strength of the pliers head 110 in one direction or a plurality of directions, so that the pliers head 110 can better act on the clamp ring 210, and the pliers head 110 can be prevented from being irreversibly deformed due to insufficient structural strength.

In some embodiments, the reinforcing portion 112 is provided on an outer peripheral surface of the base 111 facing the first direction and/or on an outer peripheral surface facing the second direction. The first direction is a movement direction when the two binding clip 110 are mutually closed, and the second direction is a movement direction when the two binding clip 110 are mutually opened. In the use process of the snap ring assembly pliers, the main stress direction of the pliers head 110 is in the movement direction of the pliers head 110, so that the reinforcing part 112 is arranged in the movement direction of the base 111 to reinforce the structural strength of the pliers head 110 in the movement direction, and the pliers have higher effectiveness.

Alternatively, the reinforcing portion 112 may be provided only on the outer peripheral surface of the base 111 in the first direction, or the reinforcing portion 112 may be provided only on the outer peripheral surface of the base 111 in the second direction, so as to reinforce the structural strength of the binding clip 110 from one side. Alternatively, reinforcing portions 112 may be provided on the outer peripheral surface of the base 111 facing the first direction and the outer peripheral surface facing the second direction, respectively, to reinforce the structural strength of the binding clip 110 from opposite sides.

In some embodiments, the reinforcing portion 112 is provided on an outer peripheral surface of the base 111 facing the third direction and/or on an outer peripheral surface facing the fourth direction. The third direction and the fourth direction are opposite, and the third direction and the fourth direction are both located between a first direction and a second direction, the first direction is a movement direction when the two pliers heads 110 are mutually closed, and the second direction is a movement direction when the two pliers heads 110 are mutually opened. Providing the reinforcing portion 112 on the outer peripheral surface of the base 111 in the third direction and/or the outer peripheral surface in the fourth direction can also increase the structural strength of the clamp head 110.

Alternatively, the angle between the third direction and the first direction may be any angle between 0 ° and 180 °. For example, the third direction may be perpendicular to the first direction. Alternatively, the outer circumferential surface of the base 111 facing in the first direction, the outer circumferential surface facing in the second direction, the outer circumferential surface facing in the third direction, and the outer circumferential surface facing in the fourth direction may or may not have a distinct dividing line therebetween. Taking the cross-sectional shape of the base 111 as an example, there is a clear dividing line between the outer peripheral surfaces of the base 111 in four directions. Taking the case where the cross section of the base 111 is circular or elliptical, there is no significant dividing line between the outer peripheral surfaces of the base 111 in the four directions. The cross section is a cross section perpendicular to the longitudinal direction of the base 111.

Alternatively, the reinforcing portion 112 may be provided on the outer peripheral surface of the base 111 facing one or more of the first direction, the second direction, the third direction, and the fourth direction. For example, the reinforcing portion 112 may be provided only on the outer peripheral surface of the base 111 facing the second direction, or the reinforcing portion 112 may be provided on the outer peripheral surfaces of the base 111 facing both the third direction and the fourth direction. Of course, in the embodiment, the reinforcing portion 112 is not limited to be provided in four directions, and the reinforcing portion 112 may be provided in a plurality of directions.

In some embodiments, the anti-slip portion 113 may be protruding on the outer circumferential surface of the clamp head 110, so that friction between the clamp head 110 and the mounting hole 211 can be increased by the anti-slip portion 113, and the clamp head 110 is prevented from being separated from the mounting hole 211 during the clamping of the clamp ring 210.

Alternatively, an anti-slip portion 113 may be provided on an outer circumferential surface of the binding clip 110 facing in the first direction. In the process of clamping the clamp ring 210 by the clamp head 110, the clamp head 110 applies pressure to the wall of the mounting hole 211 mainly through the outer circumferential surface facing the first direction so as to compress the clamp ring 210 or keep the clamp ring 210 in the current compressed state, so that the main stress surface of the clamp head 110 is the outer circumferential surface facing the first direction of the clamp head 110, and the anti-slip part 113 is arranged on the outer circumferential surface facing the first direction of the clamp head 110, so that the friction force between the clamp head 110 and the mounting hole 211 can be remarkably increased, and the clamp head has higher effectiveness.

It is to be understood that, in the embodiment, the anti-slip portion 113 is not limited to be provided on the outer peripheral surface of the binding clip 110 facing the first direction, but the anti-slip portion 113 may be provided on the outer peripheral surface of the binding clip 110 facing the other direction, or the anti-slip portion 113 may cover the entire outer peripheral surface of the binding clip 110.

In some embodiments, the anti-slip portion 113 may include one or more first ribs extending along a circumferential direction of the binding clip 110, and when the anti-slip portion 113 includes a plurality of first ribs, the plurality of first ribs are sequentially spaced apart along a length direction of the binding clip 110. The first rib extending along the circumferential direction of the binding clip 110 can significantly improve the friction force between the binding clip 110 and the hole wall of the mounting hole 211 in the length direction of the binding clip 110, thereby effectively preventing the binding clip 110 from falling out of the mounting hole 211. Alternatively, the first rib may have a ring shape, so that the first rib can cover the outer circumferential surface of the binding clip 110 in all directions. Alternatively, the first rib may have an arc shape, for example, the first rib may be protruded on an outer circumferential surface of the binding clip 110 facing the first direction.

In some embodiments, the anti-slip part 113 may include one or more rib groups, and the rib groups may include a plurality of second ribs sequentially spaced along the circumferential direction of the binding clip 110, and when the anti-slip part 113 includes a plurality of rib groups, a plurality of rib groups are sequentially spaced along the longitudinal direction of the binding clip 110. Friction between the binding clip 110 and the mounting hole 211 can also be raised by a rib group consisting of a plurality of second ribs which are sequentially provided at intervals along the circumferential direction of the binding clip 110, preventing the binding clip 110 from being separated from the mounting hole 211. Alternatively, the second rib itself may extend circumferentially of the binding clip 110.

The specific structure of the anti-slip portion 113 is merely exemplary, and the anti-slip portion 113 may be formed in various structures in the specific implementation, as long as the friction force between the clamp head 110 and the mounting hole 211 can be increased. For example, the anti-slip portion 113 may be formed by an anti-slip pattern or an anti-slip layer provided on the outer circumferential surface of the binding clip 110.

The specific structure and principles of the binding clip 110 are described in detail below with reference to the drawings and some embodiments.

As shown in fig. 2 and 3, in some embodiments, the cross-section of the base 111 and the reinforcing portion 112 may be elliptical, with the minor axis of the ellipse being disposed along the first and second directions and the major axis of the ellipse being disposed along the third and fourth directions. The base 111 is formed in a circular region having a minor axis of the ellipse as a diameter, and the reinforcement 112 is formed in other regions of the ellipse. The outer peripheral surface of the clamp head 110 is provided with an anti-slip part 113, the anti-slip part 113 comprises a plurality of first ribs, the first ribs are annular ribs extending along the circumferential direction of the clamp head 110, the outer peripheral edge of each first rib is circular, and the plurality of first ribs are sequentially arranged at intervals along the length direction of the clamp head 110.

Since the binding clip 110 needs to protrude into the mounting hole 211, the cross-sectional dimension of the binding clip 110 cannot be larger than the cross-sectional dimension of the mounting hole 211. In a limited size range, the reinforcement part 112 is provided on the outer circumferential surface of the base 111 toward the third and fourth directions, not only can the structural strength of the binding clip 110 be enhanced to a certain extent, but also the occupation of space in the first and second directions can be avoided, so that the first rib on the outer circumferential surface of the binding clip 110 toward the first and second directions has a large protrusion height, ensuring that the anti-slip part 113 can effectively increase the friction between the binding clip 110 and the mounting hole 211.

In some embodiments, the base 111 and the reinforcing portion 112 are integrally formed in a polygonal column shape, the polygonal column has a polygonal cross section, the base 111 may be formed by a cylinder having a cross section of an inscribed circle of the polygonal column within the polygonal column, and the reinforcing portion 112 may be formed by a prism portion of the polygonal column. In this way, the structural strength of the binding clip 110 can be enhanced in multiple directions.

For example, as shown in fig. 5, the base 111 and the reinforcing portion 112 may have a square cross section as a whole, the base 111 may be formed by a cylinder having a cross section of an inscribed circle of the square inside the square, and the reinforcing portion 112 may be formed by four edges of the square to reinforce the structural strength of the binding clip 110 in a plurality of directions.

Optionally, an anti-slip portion 113 may be disposed on an outer peripheral surface of the binding clip 110, and the anti-slip portion 113 may include a plurality of rib groups, which may be sequentially disposed at equal intervals along a length direction of the binding clip 110. The rib group may include four second ribs sequentially spaced apart from each other along the circumference of the binding clip 110, and the four second ribs may be respectively protruded on four sides of the regular quadrangular prism, and outer edge lines of the second ribs may be arc-shaped.

Alternatively, the four sides of the regular quadrangular prism may face the first direction, the second direction, the third direction, and the fourth direction, respectively. In this way, the second ribs disposed on the side of the regular quadrangular toward the first direction can effectively increase the friction between the binding clip 110 and the hole wall of the mounting hole 211, so as to prevent the binding clip 110 from falling out of the mounting hole 211 during the clamping of the snap ring 210.

In some embodiments, the cross-section of the polygon is a polygon, at least one diagonal of the polygon extending along the first direction. The dimension of the polygon in the diagonal direction is generally relatively large, and constructing at least one diagonal of the polygon to extend in the first direction can increase the structural strength of the binding clip 110 in the moving direction.

For example, as shown in fig. 6, the base 111 and the reinforcing portion 112 may have a generally rectangular prism shape, and the rectangular prism may have a diamond shape in cross section, and the diamond shape may have a first diagonal line and a second diagonal line having a length greater than the first diagonal line, the first diagonal line may extend in a first direction, and the second diagonal line may extend in a third direction. The base 111 may be formed by a cylinder having a cross section of the inscribed circle of the diamond shape in the right rectangular prism, and the reinforcing portion 112 may be formed by four edge portions of the right rectangular prism. The outer peripheral surface of the clamp head 110 is provided with an anti-slip part 113, the anti-slip part 113 comprises a plurality of first ribs, the first ribs are annular ribs extending along the circumferential direction of the clamp head 110, the outer peripheral edge of each first rib is circular, and the plurality of first ribs are sequentially arranged at intervals along the length direction of the clamp head 110.

In a limited size range, the second diagonal line with a relatively long length is configured to be disposed along the third direction, and the first diagonal line with a relatively short length is configured to be disposed along the first direction, so that not only can the structural strength of the clamp head 110 be enhanced to a certain extent, but also the occupation of space in the first direction and the second direction can be avoided, so that the first ribs on the outer circumferential surfaces of the clamp head 110 facing the first direction and the second direction have larger protrusion heights, and the effectiveness of the anti-skid part 113 is ensured.

As shown in fig. 7 and 8, in some embodiments, the outer peripheral surface of the base 111 facing the second direction is provided with the reinforcing portion 112, and the outer peripheral surface of the clamp head 110 facing at least the first direction is provided with an anti-slip portion 113. Since the binding clip 110 needs to protrude into the mounting hole 211, the cross-sectional dimension of the binding clip 110 cannot be larger than the cross-sectional dimension of the mounting hole 211. In a limited size range, the reinforcing portion 112 is disposed on the outer peripheral surface of the base 111 facing the second direction, so that not only the structural strength of the clamp head 110 in the movement direction can be increased, but also the space of the clamp head 110 facing the first direction occupied by the reinforcing portion 112 can be avoided, so that the anti-slip portion 113 can be disposed on the outer peripheral surface of the clamp head 110 facing the first direction, thereby effectively increasing the friction force between the clamp head 110 and the mounting hole 211, and realizing the dual purposes of effectively increasing the friction force of the clamp head 110 and the structural strength in the movement direction.

Alternatively, the reinforcement portion 112 may be formed by a thickened structure protruding from the outer peripheral surface of the base 111, the cross section of the thickened structure may be in a sector shape, one end of the thickened structure may be connected to the end surface of the clamp rod 120, and the other end of the thickened structure may extend to a position close to the free end of the base 111.

Alternatively, the anti-slip portion 113 may include a plurality of first ribs disposed on an outer peripheral surface of the base 111 facing the first direction, the plurality of first ribs may be disposed in sequence along a length direction of the base 111 at equal intervals, the first ribs may extend along a circumferential direction of the base 111 and be arc-shaped, and two ends of the first ribs may be engaged with two sides of the thickening structure. Alternatively, the outer diameter of the first rib may be the same as the outer diameter of the thickened structure to maximize the size of both the reinforcing portion 112 and the anti-slip portion 113.

In some embodiments, the free end of the binding clip 110 is provided with a guide 114. The guide portion 114 facilitates smooth insertion of the binding clip 110 into the mounting hole 211, which is beneficial to improving user experience. Alternatively, the guide 114 may be formed by a guide slope or a guide arc surface.

For example, in the embodiment illustrated in fig. 2 and 3, the end face of the free end of the binding clip 110 may be configured to be a raised arcuate shape to form the guide 114.

Also for example, in both embodiments illustrated in fig. 5 and 6, at the free end of the quadrangular prism, four sides of the quadrangular prism may extend axially and converge toward the hub to form a guide structure that approximates a pyramid.

For another example, in the embodiment illustrated in fig. 7 and 8, the base 111 has a cylindrical shape, a guiding arc surface with a tapered diameter may be provided at the free end of the base 111, and furthermore, the thickened structure may be configured to have a reduced thickness near the free end of the base 111 to form another guiding arc surface, by which the guiding portion 114 of the binding clip 110 is jointly constituted.

In some embodiments, one jaw body 100 of the two jaw bodies 100 further includes a rack 140, one end of the rack 140 is connected to the jaw handle 130 or is connected near the other end of the jaw rod 120, and the other end of the rack 140 extends toward the direction near the other jaw body 100; the other jaw 100 further includes a ratchet (not shown) provided on the grip 130 or the jaw bar 120, for being engaged with the rack 140 to maintain the current posture of the two jaw 100, as shown in fig. 9. In the use process, the clamping state is kept without the need of medical staff to continuously hold and press the clamp handles 130, so that labor is saved, and accurate assembly of the hip joint prosthesis is facilitated. In the process of storage, the clamp body 100 can be prevented from opening automatically, and the clamp body is beneficial to orderly storage. Alternatively, the rack 140 may be configured to extend along a first circumference, the center of which may coincide with the center of rotation of the two clamp bars 120, and maintain a uniform width during extension.

Optionally, the first identifier 141 is used to identify the relative positions of the two clamp bodies 100, so as to facilitate medical staff to accurately control the opening and closing dimensions of the clamp head 110, and further accurately control the state of the clamp ring 210, and facilitate the installation of the clamp ring 210. For example, a plurality of graduation marks and a plurality of numerical values may be sequentially arranged at equal intervals along the length direction of the rack 140, and an alignment mark such as an arrow may be arranged on the other pliers body 100, so that the opening and closing size of the pliers head 110 can be accurately identified through the cooperation of the arrow and the graduation marks. It is understood that the first mark 141 is not limited to a scale mark, but may be other marks that can mark the opening and closing degree of the two clamp heads 110.

The above embodiments are only exemplary embodiments of the present utility model and are not intended to limit the present utility model, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this utility model will occur to those skilled in the art, and are intended to be within the spirit and scope of the utility model.
