Detailed Description

The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1-6, the utility model provides a clinical novel piercing depth of heart chest surgery, including fixed disk 8, fixed surface is connected with support box 9 on the fixed disk 8, support box 9 inner wall and install the fixed pipe 13 that can reciprocate, detachable pjncture needle 6 is installed to fixed pipe 13 inner wall, fixed pipe 13 surface upper end fixedly connected with annular slab 16, annular slab 16 upper end fixed surface is connected with a screw thread section of thick bamboo 22, surface mounting has the even arc splint 18 of three distribution on the screw thread section of thick bamboo 22, screw thread section of thick bamboo 22 surface threaded connection has round handle 17, can constitute three arc splint 18 and fold or open structure to the outside to the inboard simultaneously when round handle 17 rotates.

As shown in fig. 1-3 or 6, the lower end surface of the fixed disk 8 is provided with a glue surface, the fixed disk 8 can be fixed on the skin surface of a patient through the glue surface so as to fix and clamp the whole device, and the puncture needle 6 can be punctured into the thoracic cavity of the patient through the fixing tube 13 which can move up and down; inside puncture needle 6 inserted fixed pipe 13, there is not the relation of connection, can fold to the inboard simultaneously through making three arc splint 18, press from both sides tight fixedly to fixed pipe 13 upper end, thereby make puncture needle 6 press from both sides tight fixedly, because puncture needle 6 and fixed pipe 13 have certain frictional force, when the clamp force of arc splint 18 is enough big, through the fixed pipe 13 that can reciprocate, can drive puncture needle 6 lower extreme and get into to the thorax inside of patient, because the V-arrangement groove has been seted up to fixed pipe 13 upper end, the variable size of upper end opening part, make things convenient for puncture needle 6 to insert inside fixed pipe 13.

Rotatable handle 10 is installed to support case 9 rear end, the coaxial rigid coupling of handle 10 front end has spur gear 11, fixed pipe 13 surface rear end fixedly connected with spur rack 12, spur rack 12 meshes with spur gear 11 mutually, fixed pipe 13 surface front end fixedly connected with slide 14, support case 9 front end inner wall fixedly connected with limiting plate 15, slide 14 sliding connection is at limiting plate 15 inner wall.

As shown in fig. 3-5, a rotating shaft is fixedly connected at the center of the handle 10 and the straight gear 11, and the rotating shaft is rotatably connected to the inner wall of the supporting box 9; the sliding plate 14 and the limiting plate 15 are used for limiting the fixing pipe 13 to move only up and down; through rotating the handle 10, the handle 10 rotates to drive the spur gear 11 to rotate, the spur gear 11 rotates to drive the spur rack 12 to move up and down through meshing, the spur rack 12 moves up and down to drive the fixing tube 13 to move up and down, and the fixing tube 13 moves up and down to drive the puncture needle 6 to move up and down, so that the puncture needle 6 can be penetrated into a thoracic cavity of a patient.

The inner wall of the upper end of the round handle 17 is fixedly connected with three first guide rods 19 which are uniformly distributed, the inner wall of the upper end of the outer side of the arc-shaped clamping plate 18 is respectively hinged with a first connecting rod 20, the inner wall of the lower end of the outer surface of the arc-shaped clamping plate 18 is respectively hinged with a second connecting rod 21, the other end of each first connecting rod 20 is respectively connected to the outer surface of the corresponding first guide rod 19 in a sliding mode, and the other end of each second connecting rod 21 is respectively hinged to the upper end surface of the corresponding.

The installation drawings of the first connecting rod 20, the second connecting rod 21, the first guide rod 19 and the arc-shaped clamping plate 18 are shown in fig. 6, a thread groove matched with the outer surface of the thread cylinder 22 is formed in the inner wall of the round handle 17, cylindrical through holes are formed in the center of the thread cylinder 22 and the center of the round handle 17 respectively, and the fixing pipe 13 penetrates through the inner wall of each cylindrical through hole; through rotating round handle 17, round handle 17 rotates and to drive three first guide arm 19 and rotate, three first guide arm 19 rotates and then can drive corresponding first connecting rod 20 and rotate, can make the contained angle between first connecting rod 20 and the second connecting rod 21 diminish when first connecting rod 20 rotates, arc splint 18 can move to the inboard this moment, then can press from both sides tight fixedly to fixed pipe 13, because two of threaded cylinder 22 and round handle 17 belong to threaded connection, there is the space of reciprocating of a small amount when round handle 17 rotates, so first guide arm 19 and first connecting rod 20 sliding connection, thereby realize driving corresponding first connecting rod 20 and rotate, when arc splint 18 presss from both sides tightly fixed pipe 13, because threaded cylinder 22 and round handle 17 threaded connection have great frictional force, so arc splint 18 and fixed pipe 13 can not easily produce when advancing the needle and slide.

The surface of the upper end of the puncture needle 6 is provided with a detachable second connecting pipe 5, the other end of the second connecting pipe 5 is fixedly connected with a drainage bottle 3, the surface of the left end of the drainage bottle 3 is fixedly connected with a first connecting pipe 2, and the other end of the first connecting pipe 2 is fixedly connected with a negative pressure sac 1.

As shown in fig. 1-2, the puncture needle 6 and the first connecting tube 2 are in interference fit, the negative pressure bag 1 is made of soft material and has high elasticity, the negative pressure bag 1 is pinched flat before use, and after the puncture needle 6 enters the body of a patient, the air in the negative pressure bag 1 presents negative pressure by loosening the negative pressure bag 1, so that the liquid in the thoracic cavity of the patient can be pumped into the drainage bottle 3; through the apparent elastic deformation of negative pressure bag 1, can present the negative pressure state that lasts to can replace piston device, because there is the negative pressure state always in the piston device cavity, need medical personnel to move outward the piston board always, but this process medical personnel can not break away from handheld, and elastic deformation through negative pressure bag 1 presents the continuation to the negative pressure in drainage bottle 3, can swing medical personnel's handheld breaking away from, thereby carries out the drainage to patient's pleural effusion.

When the utility model is used, the three arc-shaped clamping plates 18 are folded inwards by rotating the round handle 17, so that the fixing tube 13 and the puncture needle 6 are fixed, the puncture needle 6 is prevented from being separated from causing secondary injury, and the fixing disc 8 is fixed at the thoracic cavity of a patient by flattening the negative pressure bag 1; because every patient's fat thin difference, through turning handle 10, can make pjncture needle 6 pierce patient's thorax inside, and can be effective convenient control pjncture needle 6 the depth of inserting needle.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or scope of the invention as defined in the appended claims.
