Abstract
The utility model discloses a special depth measurement guider of collar -bone hollow rivet, including position sleeve and guide pin, the guide pin front end has sharp portion, and the rear end is an end, and in the guide pin front end inserted the position sleeve, the tip outside was equipped with handheld handle behind the position sleeve, is equipped with the spring button of symmetric distribution on the position sleeve of handheld handle rear end position, the equal fixedly connected with of every the spring button lower extreme splint that lead, the guide pin on be equipped with the scale mark. The utility model overcomes prior art's is not enough, reasonable in design, compact structure, the cooperation of position sleeve and guide pin, can quick, accurate depth measurement and supplementary direction put the nail, convenient operation, the control of being convenient for.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically belongs to the special depth measurement guider of clavicle hollow nail.
Background technology
In clinical position, extremity fracture is the common disease of Bone and joint trauma.Bone traction or extenal fixation are one of common methods of early treatment's extremity fracture, when carrying out Bone traction or extenal fixation, guide pin or the horizontal vertical drill of drill bit is needed to enter sclerotin, the key point of this operation is the axis oriented normal of guide pin or drill bit and backbone, then hollow nail is driven in bone by guide pin, existing guide pin only plays single guide effect, do not possess depth measurement effect, as the length of required hollow nail need be measured, also need special depth finder, use loaded down with trivial details, auxiliary directional orientation tool is lacked when importing, experience mainly by performing doctor is done, what produce differs greatly, result of use is difficult to hold.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided the special depth measurement guider of clavicle hollow nail, overcomes the deficiencies in the prior art, reasonable in design, compact conformation, positioning sleeve and guide pin coordinate, can fast, accurately depth measurement and auxiliary guiding put nail, easy to operate, be convenient to control.
The technical solution adopted in the utility model is as follows:
The special depth measurement guider of clavicle hollow nail, comprise positioning sleeve and guide pin, described guide pin front end has tip, rear end is an end, guide pin front end is inserted in positioning sleeve, hand holding handle is provided with outside positioning sleeve rearward end, the positioning sleeve of hand holding handle back-end location is provided with symmetrical spring button, each spring button lower end is all fixedly connected with guiding clamping plate, can will carry out outside guide pin reducing parcel, make guide pin can locate derivation more accurately, after guide pin leads suitable position, by lower spring case, guiding clamping plate rise, afterwards just can be by, hollow nail is inserted on guide pin, described guide pin is provided with graduation mark.
Described symmetrical spring button has multipair, distributes around positioning sleeve even circumferential.
Described hand holding handle is connected with the part that is connected through the hinge between positioning sleeve.
Described hand holding handle is bellows structure.
Compared with the prior art, the beneficial effects of the utility model are as follows:
This utility model compares existing hollow nail in implantation pulp cavity process without the protection of located in connection cover; because hollow nail front end is with cutting screw thread; easily unnecessary destruction is caused to peripheral soft tissues; and this utility model positioning sleeve and guide pin coordinate, can fast, accurate depth measurement and auxiliary guiding put nail, easy to operate; be convenient to control; maximum possible can reduce skin incision and soft tissue injury, reduce operating procedure, reach Wicresoft's effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that Figure 1A-A analyses and observe.
Detailed description of the invention
See accompanying drawing, the special depth measurement guider of clavicle hollow nail, comprise positioning sleeve 1 and guide pin 2, guide pin 2 front end has tip 201, rear end is an end, guide pin 2 front end is inserted in positioning sleeve 1, hand holding handle 3 is provided with outside positioning sleeve 1 rearward end, the positioning sleeve of hand holding handle 3 back-end location is provided with multipair symmetrical spring button 4, multipair spring case 4 distributes around positioning sleeve even circumferential, each spring button lower end is all fixedly connected with guiding clamping plate 5, can will carry out outside guide pin reducing parcel, make guide pin 2 can locate derivation more accurately, after guide pin leads suitable position, by lower spring case, guiding clamping plate 5 rise, afterwards just can be by, hollow nail is inserted on guide pin, described guide pin 2 is provided with graduation mark 202, described hand holding handle 3 is connected with the part 301 that is connected through the hinge between positioning sleeve, hand holding handle is bellows structure, can according to practical operation situation, hand holding handle can suitably be out of shape, convenient operation.
Use operation committed step, by guide pin tip skin after the clavicle broken ends of fractured bone punctures acromion to clavicle far-end, the head that will pause again is placed in clavicle near-end (head is inserted clavicle near-end and is conducive to reducing the danger that guide pin enters thoracic cavity), after the reduction of the fracture is satisfied, after acromion, guide pin afterbody opens direct about 8mm (equaling a positioning sleeve diameter) osculum, positioning sleeve is inserted along guide pin direction (insert positioning sleeve in process and play the effect of blunt separation perienchyma), positioning sleeve far-end withstands clavicular cortex, read the numerical value of guide pin afterbody and positioning sleeve tail end before this, this numerical value is the length of required hollow nail, select this scale hollow nail, along positioning sleeve protection, (now positioning sleeve plays protection peripheral soft tissues, prevent soft tissue from being stirred into by screw thread) under guide through guide pin, insert hollow nail smoothly, after inserting hollow nail, first guide pin is taken out at acromial end, extract positioning sleeve again.
This utility model compares existing hollow nail in implantation pulp cavity process without the protection of located in connection cover; because hollow nail front end is with cutting screw thread; easily unnecessary destruction is caused to peripheral soft tissues; and this utility model positioning sleeve and guide pin coordinate, can fast, accurate depth measurement and auxiliary guiding put nail, easy to operate; be convenient to control; maximum possible can reduce skin incision and soft tissue injury, reduce operating procedure, reach Wicresoft's effect.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
