Abstract
The purpose of the present invention is to propose to a kind of dilators and its application method with holes, for reducing operation wound and difficulty in minimal access bone.Dilator with holes of the invention includes two calipers for being symmetrical arranged and being connected by shaft, and key is that the front end of described two calipers is equipped with through-hole, and the axial direction of the through-hole is axial parallel with shaft.When during bone surgery, when target bone location is deeper, first needle body (such as saying the common Kirschner wire of bone surgery) can be inserted near targeted bone at the soft tissue of two sides, and the through-hole of two caliper front ends is covered on corresponding needle body, then without in the case where expanding surgical wound, needle body can be driven to strut soft tissue using caliper, targeted bone be exposed, to carry out subsequent surgical procedure.The present invention has done on traditional dilator and has cleverly changed, and allows to cooperate with needle body, to strut the deeper soft tissue in position, facilitates the operation of operation, has good practicability.
Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of minimally invasive soft tissue support in bone surgery
Open instrument and the application method of the dilator.
Background technique
In bone surgery, it usually needs give away one's position bone, to reach therapeutic purposes.In minimally invasive situation, due to cutting
Small, deeper for the position targeted bone of mouth, usual difficult exposure need prolonged incison, until the bone that gives away one's position, increases operation
Wound causes operating time to extend, and operating difficulty increases.
Summary of the invention
The purpose of the present invention is to propose to the application methods of a kind of dilator and the dilator with holes, to be used for minimally invasive orthopaedics
In operation, operation wound and difficulty are reduced.
Dilator with holes of the invention includes two calipers for being symmetrical arranged and being connected by shaft, and key is described
The front end of two calipers is equipped with through-hole, and the axial direction of the through-hole is axial parallel with shaft.
The application method of above-mentioned dilator with holes is as follows: in bone surgery, when target bone location is deeper, first by needle body
It is inserted near targeted bone at the soft tissue of two sides, and the through-hole of two caliper front ends is covered on corresponding needle body, then exist
In the case where expanding surgical wound, drives needle body to strut soft tissue using caliper, targeted bone is exposed, to carry out hand
Art operation.Specifically, above-mentioned needle body is common Kirschner wire in bone surgery.
Further, which further includes a tooth plate, in described two calipers, the rear end of caliper and tooth plate
One end is hinged, and tooth plate is equipped with rack gear towards the end face of caliper, and the rear end of another caliper is equipped with the latch that can be caught in rack gear.It is supportting
It opens after device reaches and be satisfied with position, latch is caught in rack gear, so that the aperture of fixed dilator, keeps the distraction angle of dilator
Stablize.
Further, the lateral surface of the caliper is equipped with anti-skid chequer, is held with facilitating.
The present invention has done on traditional dilator and has cleverly changed, allow to needle body cooperate, with strut position compared with
Deep soft tissue, facilitates the operation of operation, has good practicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of dilator of the invention.
Attached drawing mark: 1, caliper；2, shaft；3, through-hole；4, tooth plate；5, latch.
Specific embodiment
It is for example related each to a specific embodiment of the invention by the description to embodiment below against attached drawing
The shape of component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. are made into one
The detailed description of step.
Embodiment 1:
The present embodiment proposes a kind of dilator and its application method with holes, can cooperate with needle body, minimally invasive lower to soft group
It knits and is strutted, give away one's position bone, to reduce operation wound and difficulty.
As shown in Figure 1, the dilator with holes of the present embodiment includes a tooth plate 4 and is symmetrical arranged and passes through shaft 2
The outside of two calipers 1 of connection, caliper 1 is equipped with anti-skid chequer, and the front end of two calipers 1 is equipped with through-hole 3, the through-hole 3
It is axial axial parallel with shaft 2；In two calipers 1, the rear end of a caliper 1 and one end of tooth plate 4 are hinged, 4 direction of tooth plate
The end face of caliper 1 is equipped with rack gear, and the rear end of another caliper 1 is equipped with the latch 5 that can be caught in rack gear.
The application method of above-mentioned dilator with holes is as follows: when during bone surgery, when target bone location is deeper,
Needle body (such as the Kirschner wire for saying the common diameter 3.0mm of bone surgery) first can be inserted into soft group of two sides near targeted bone
Place is knitted, and by 3 sets of the through-hole of two 1 front ends of caliper on corresponding needle body, then in the case where being not necessarily to expand surgical wound,
Needle body can be driven mobile using caliper 1, soft tissue is strutted, targeted bone is exposed, latch 5 is then caught in tooth plate 4
Rack gear, so that the aperture of fixed dilator, makes the distraction angle of dilator keep stablizing, to carry out subsequent surgical procedure.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention specifically designs not by aforesaid way
Limitation, if use the improvement for the various unsubstantialities that conception and technical scheme of the invention carry out, or it is not improved will
Conception and technical scheme of the invention directly apply to other occasions, within the scope of the present invention.
Claims (5)
