Description
Technical Field
The invention relates to the field of surgical instruments, in particular to an anti-skidding structure used for a holding part in a surgical instrument.
Background
In surgery, the attending physician often uses a number of medical instruments to assist in performing the procedure, such as staplers, ligators, and hemostats. However, blood often splashes out during the operation, and when the medical instrument or the medical gloves of the doctor are stained with blood, the doctor can easily slip when holding the medical instrument by hand, which is very dangerous.
The anti-skidding structure is generally used for being provided with a plurality of salient points on a holding surface, but in the practical process, the anti-skidding effect of the structure is not obvious, because medical gloves used by doctors are generally made of latex materials and are stained with blood or other liquid, the frictional resistance between the common salient points and the medical gloves is greatly reduced, and the anti-skidding effect is not achieved.
Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.
Disclosure of Invention
The invention aims to provide an anti-skid structure of a gripping surface of a surgical operation instrument
In order to achieve the purpose, the invention adopts the technical scheme that:
the anti-skid structure of the holding surface of the surgical operation instrument is characterized in that a plurality of anti-skid salient points are distributed on the holding surface of the surgical operation instrument; the definition is that the outer part relative to the holding surface is a high part and the inner part relative to the holding surface is a low part by taking the holding surface as a reference:
each anti-skid salient point comprises a bottom frame, three convex ribs and three webbed concave surfaces;
the bottom frame is a triangular frame formed by three bottom edges in a surrounding mode, each bottom edge is a slope surface inclining towards the lower part, one relatively higher side of each slope surface is connected with the holding surface to form the outer edge of the bottom frame, one relatively lower side of each slope surface is connected in the triangular frame to form the inner edge of the bottom frame, and therefore the inwards concave bottom frame is formed;
one end of each convex rib is fixedly arranged on one corner of the bottom frame, the other end of each convex rib inclines towards the high position and extends to the center of the triangular frame, the three convex ribs correspond to the three corners of the bottom frame one by one, and the three corners of the bottom frame are converged to a common point of the high position to form a three-leg convex structure in the triangular frame, and the common point is the peak of the three-leg convex structure;
in the three-leg convex structure, an included angle is formed between two adjacent convex ribs, and a triangular space is formed by the two convex ribs forming the included angle and the bottom edge corresponding to the included angle;
three triangular spaces are arranged in each anti-skid convex point, three webbed concave surfaces are correspondingly paved in each triangular space one by one, and each webbed concave surface is a concave surface sunken to the lower part and is connected between the triangular frame and the three-foot convex structure to form a sunken space on the anti-skid convex point;
the anti-skidding structure still includes a plurality of groups of bump arrays, and a plurality of groups of bump arrays are laid on the face of gripping of surgical operation apparatus, each group the bump array comprises three to six anti-skidding bumps, and in every group bump array, the summit evenly distributed of each anti-skidding bump is on the circle of same circle, and the underframe of each anti-skidding bump all has the centre of a circle of the directional this circle of one corner to this constitutes each anti-skidding bump in the bump array and evenly arranges to the heart.
Furthermore, each bottom edge is a slope surface which inclines towards the lower part, one relatively higher edge of each bottom edge is connected with the holding surface to form the outer edge of the bottom frame, and one relatively lower edge of each bottom edge is connected with the triangular frame to form the inner edge of the bottom frame, so that the concave bottom frame is formed;
each bottom edge can also be a slope surface inclined towards a high position, one relatively lower side of each bottom edge is connected on the holding surface to form the outer edge of the bottom frame, one relatively higher side of each bottom edge is connected in the triangular frame to form the inner edge of the bottom frame, so that the upwards-convex bottom frame is formed, and the web-shaped concave surface connected between the upwards-convex bottom frame and the convex rib can still form a concave space;
the bottom edges can also be all non-inclined slopes, so that a bottom frame which is positioned on the same surface with the holding surface is formed, and the webbed concave surface connected between the bottom frame and the convex rib can still form a sunken space.
Furthermore, among the three bottom edges on the bottom frame, the joint of two adjacent bottom edges is a fillet.
Furthermore, the outer surface of the convex rib is an arc curved surface, so that the webbed concave surfaces connected to the two sides of the convex rib form curved surface transition.
Furthermore, on the three-leg convex structure, the vertex formed by the three convex ribs is a spherical surface; the vertex can be a convex spherical surface or a concave spherical surface.
Furthermore, the curvature of the holding surface is a variable value, and the number of the anti-skid convex points in the convex point array at the position with higher curvature is greater than that of the convex point array at the position with lower curvature on the holding surface.
Furthermore, the curvature of the holding surface is a variable value, and the height difference between the bottom frame and the top point of each anti-slip bump in the bump array at the position with higher curvature is greater than the height difference between the bottom frame and the top point of each anti-slip bump in the bump array at the position with lower curvature.
Furthermore, the curvature of the holding surface is a variable value, and the inward concave degree of the webbed concave surface of each anti-skid convex point in the convex point array at the position with higher curvature is greater than the inward concave degree of the webbed concave surface of each anti-skid convex point in the convex point array at the position with lower curvature.
The relevant content in the above technical solution is explained as follows:
1. in the scheme, the three convex ribs form a three-leg convex structure, so that a plurality of protrusions are formed on the holding surface, the friction force between the holding surface and the medical gloves is increased, and the anti-skidding function can be achieved.
2. In the scheme, the webbed concave surface is connected between the triangular frame and the tripod protruding structure to form a sunken space, when the medical gloves stained with bloody water cover the anti-skidding convex points, the medical gloves and the sunken space can form a vacuum cavity, so that the webbed concave surface forms a structure similar to a sucker, an adsorption effect can be formed between the medical gloves, and compared with common convex points, the convex points with the webbed concave surface still have an anti-skidding effect in a water staining state.
3. In the scheme, the salient point array is formed by uniformly and centripetally arranging a plurality of anti-skidding salient points, so that when the medical glove is held, a palm wearing the medical glove can uniformly apply pressure to each webbed concave surface in the salient point array, and the medical glove is similar to a plurality of suckers which are simultaneously adsorbed on the glove; in the process that the palm contacts the holding surface, the effect of the palm on the webbed concave surface is diffused from one convex point to other convex points, then is diffused to the whole convex point array, and is finally diffused to a plurality of convex point arrays, so that a plurality of webbed concave surface adsorption points are acted on the glove, and a good anti-skidding effect is achieved;
the array combination is formed by surrounding three to six anti-skid convex points, the surrounding center of the array combination is still a smooth surface on the holding surface, the arrangement mode can ensure that all the anti-skid convex points are regularly and densely distributed, the curved surface area on the holding surface and the sunken area of the web-shaped concave surface form a reasonable proportion, so that when a doctor uses the surgical medical instrument, the holding surface has a higher adsorption rate to the palm, the anti-skid effect is improved, the condition that the adsorption effect is poor due to too few convex points is avoided, and the web-shaped concave surface is changed into a relatively smooth surface due to too dense convex points, and the adsorption function is lost.
4. In the scheme, when the bottom edge is a slope inclined towards the lower part, the webbed concave surface can be matched to form a sunken space, so that the salient point has a larger sunken space, and the adsorption effect is better;
when the bottom edge is a slope surface inclined to a high position or a slope surface not inclined, the lowest sunken point of the webbed concave surface is lower than the holding surface, and under the two structures, the salient points still have sunken spaces and still have an adsorption effect on the medical gloves.
5. In the scheme, the connecting part of two adjacent bottom edges is a round angle, and compared with a sharp corner, the structure is smooth in transition, so that the palm has more comfortable touch feeling when being held.
6. In the scheme, the outer surface of the convex rib is an arc curved surface, so that the web-shaped concave surfaces connected to the two sides of the convex rib form smooth curved surface transition, and the palm has more comfortable touch when holding.
7. In the scheme, the vertex formed by the three convex ribs is a spherical surface, and if the vertex is a convex spherical surface, smooth curved surface transition can be formed, so that the palm has more comfortable touch feeling when being held;
if the top point is an inwards concave spherical surface, an inwards concave space can be formed, and the webbed concave surface is matched to adsorb the medical gloves together, so that the anti-skidding effect is improved.
8. In the above scheme, in a use state, the force applied by the palm to the higher curvature part of the holding surface is greater than the force applied to the lower curvature part of the holding surface, so that the number of the anti-skid convex points of the convex point array in the higher curvature part of the holding surface is greater than the number of the anti-skid convex points of the convex point array in the lower curvature part of the holding surface, so as to improve the adsorption rate and improve the anti-skid effect.
9. In the above scheme, when a doctor uses a surgical medical instrument, the force applied by the palm to the higher curvature part of the holding surface is greater than the force applied to the lower curvature part of the holding surface, so that the fitting degree of the palm to the higher curvature part of the holding surface is higher, therefore, each anti-skid convex point of the convex point array in the higher curvature part of the holding surface has a height difference between the bottom frame and the vertex greater than the height difference between the bottom frame and the vertex of each anti-skid convex point of the convex point array in the lower curvature part of the holding surface, and the height difference is higher, namely, the height of the convex point relative to the holding surface is higher, so that the frictional resistance between the convex point and the palm can be improved, and the anti-skid effect is improved.
10. In the above scheme, when the doctor uses the surgical medical instrument, the palm is exerted the power of the higher position of curvature is greater than the power of the lower position of curvature of application on the surface of gripping to the laminating degree of the higher position of curvature of palm on the surface of gripping is higher, therefore each anti-skidding bump of the higher position of curvature salient point array in the surface of gripping, its the indent space of web form concave surface is greater than the indent space of the web form concave surface of each anti-skidding bump of the lower position of curvature salient point array in the surface of gripping, and the indent space is the bigger, and the adsorption force is the bigger, and the better is the anti-skidding effect.
The working principle of the invention is as follows:
each anti-slip salient point comprises a bottom frame, three convex ribs and three webbed concave surfaces; the bottom frame is a triangular frame, three convex ribs are converged to a vertex in the bottom frame to form a three-foot convex structure in the triangular frame, three web-shaped concave surfaces are laid in the three-foot convex structure, the web-shaped concave surfaces are concave surfaces sunken to the lower part, each web-shaped concave surface is connected between the triangular frame and the three-foot convex structure to form a sunken space, when a doctor brings medical gloves to contact with a holding surface, a vacuum cavity can be formed on the web-shaped concave surfaces to generate adsorption force, the anti-skid effect is enhanced, and a group of convex point arrays are formed by the anti-skid convex points, so that the adsorption effect is better.
The invention has the following advantages:
1. the antiskid effect is good: the webbed concave surfaces of the anti-skid convex points are concave surfaces, so that a vacuum cavity can be formed between the anti-skid convex points and the medical gloves, adsorption force is generated, and the anti-skid effect is improved.
2. The hand feeling of holding is good: three corners of the bottom edge are round corners, the outer surfaces of the convex ribs are arc curved surfaces, and the vertexes of the three convex ribs are spherical surfaces which are smooth curved surfaces, so that the hand-held electric toothbrush cannot generate pressure pain and is good in hand feeling.
3. The bump distribution rule, the antiskid effect is better: the plurality of salient points form a salient point array, and when the curvature of the holding surface changes, the quantity and specification parameters of the salient points in the salient point array also change, so that the optimal anti-skidding effect is achieved.
