Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-2, the present invention provides the following technical solutions: a needle holding forceps for general surgery comprises a rectangular rod 1, a first shearing force arm 4 and a second shearing force arm 5, wherein a rectangular groove 2 is formed in the front end of the rectangular rod 1, a pin shaft 3 is fixedly inserted in the middle of the rectangular groove 2, the middle of the pin shaft 3 is movably inserted in the center of the first shearing force arm 4 and the center of the second shearing force arm 5, one end, protruding out of the rectangular groove 2, of the first shearing force arm 4 is fixedly connected with a first clamping plate 6, one end, protruding out of the rectangular groove 2, of the second shearing force arm 5 is fixedly connected with a second clamping plate 7, three pairs of needle head clamping grooves 8 are symmetrically arranged on one side, opposite to the first clamping plate 6 and the second clamping plate 7, a rectangular pipe 9 is movably nested on the outer side of the rectangular rod 1, two arc pressing heads 10 are fixedly connected to the front end of the rectangular pipe 9 in a mirror image manner, the two arc pressing heads 10 intermittently press the outer sides of the tail ends of the first shearing force arm, an application ring 12 is vertically fixed on the bottom side of the tail end of the rectangular tube 9.

In this embodiment, when in use, the palm of the medical staff holds the handle 11, the fingers of the handle hook the force applying ring 12 to pull the rectangular tube 9, when the rectangular tube 9 moves backwards along the rectangular rod 1, the two arc pressing heads 10 are driven to press the outer sides of the tail ends of the first shearing force arm 4 and the second shearing force arm 5, at this time, according to the lever principle, the first clamping plate 6 and the second clamping plate 7 at the front ends of the first shearing force arm 4 and the second shearing force arm 5 are close to each other, the first clamping plate 6 and the second clamping plate 7 are close to the tail end of the surgical needle which is matched with the first clamping plate through any one pair of the three pairs of needle clamping grooves 8 after being integrated, at this time, the surgical site can be sutured through the head end of the surgical needle, compared with the common surgical needle holding forceps, the utility model discloses the operation is more convenient, the clamping is firmer, and the secondary injury to the;

after the force applying ring 12 is loosened, the two arc pressing heads 10 do not press the outer sides of the tail ends of the first shear arm 4 and the second shear arm 5, at the moment, the first clamping plate 6 and the second clamping plate 7 are far away from each other, and thus, the clamped surgical needle is loosened.

Specifically, the spring 13 is connected in series in the middle of the tail end of the rectangular rod 1, and the spring 13 elastically abuts against the tail end of the rectangular tube 9.

In this embodiment, spring 13 elasticity contradicts the tail end of rectangular pipe 9, promotes rectangular pipe 9 and stretches forward, so when operating personnel loosens one's hand, rectangular pipe 9 resets under the elastic force effect for two automatic releases of circular arc pressure head 10 touch the pressure of first shear force arm 4 and the 5 tail ends of second shear force arm, make its automatic pine open the operation needle of first splint 6 and the centre gripping of second splint 7, be convenient for adjust the clamping position of operation needle body, and repeated centre gripping and unclamp the state.

Specifically, the first clamping plate 6 and the second clamping plate 7 are provided with inclined needle clamping grooves 14, and the inclined needle clamping grooves 14 and the three pairs of needle clamping grooves 8 are mutually staggered.

In this embodiment, when the suture angle of the surgical needle is small, the inclined needle clamping groove 14 is used to clamp the currently used surgical needle, so as to facilitate the suture of medical staff.

Specifically, the groove diameters of the three pairs of needle head clamping grooves 8 gradually increase from the front end to the rear end.

In this embodiment, the groove footpath of three pairs of syringe needle draw-in grooves 8 is progressively increased by front end to rear end, so at the thin, the shorter operation needle of length of the front end centre gripping diameter of first splint 6 and second splint 7 to carry out meticulous operation and sew up, at the thick, the longer operation needle of length of the rear end centre gripping diameter of first splint 6 and second splint 7, so that to the firm centre gripping of this operation needle.

Specifically, the outsides of the first shear arm 4 and the second shear arm 5 are of an outwards-turned arc plate structure.

In this embodiment, the outside of the first shearing force arm 4 and the second shearing force arm 5 is an arc plate structure that turns up, so when the arc pressure head 10 presses and touches the outside of the first shearing force arm 4 and the second shearing force arm 5, the pressing force can be better applied to the first shearing force arm 4 and the second shearing force arm 5, so that the clamping surgical needle that the first clamping plate 6 and the second clamping plate 7 are fastened through the needle head clamping groove 8 or the inclined needle clamping groove 14 is driven by the clamping surgical needle.

The rectangular bar 1 in this embodiment is a known technique that has been disclosed to be widely used in industrial production and daily life.

The utility model discloses a theory of operation and use flow: the palm of a medical worker holds a handle 11, fingers of the medical worker hook a force application ring 12 to pull a rectangular tube 9, when the rectangular tube 9 moves backwards along a rectangular rod 1, two arc pressing heads 10 are driven to press and touch the outer sides of the tail ends of a first shearing force arm 4 and a second shearing force arm 5, at the moment, according to the lever principle, a first clamping plate 6 and a second clamping plate 7 at the front ends of the first shearing force arm 4 and the second shearing force arm 5 are close to each other, the first clamping plate 6 and the second clamping plate 7 are close to the tail ends of surgical needles matched with the first clamping plate and the second clamping plate through any pair of three pairs of needle head clamping grooves 8 after being integrated, at the moment, the surgical parts can be sutured through the head ends of the surgical needles, after the force application ring 12 is loosened, the two arc pressing heads 10 do not press and touch the outer sides of the tail ends of the first shearing force arm 4 and the second shearing force arm 5, at the moment, the first clamping plate 6 and; spring 13 has been concatenated in the middle part of 1 tail end of rectangular pole, spring 13 elasticity is contradicted the tail end of rectangular pipe 9 and is promoted its protraction, so when operating personnel is loose, rectangular pipe 9 resets under the elastic force effect, make two automatic pressure contacts to the pressure of the 5 tail ends of first shearing force arm 4 and the second shearing force arm of loosening of circular arc pressure head 10, make its automatic operation needle of opening first splint 6 and the centre gripping of second splint 7 of loosening, be convenient for adjust the clamping position of operation needle body, and repeated centre gripping and unclamp the state.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
