Description
Technical field
The present invention relates to a kind of bone surgery set to relate to particularly and hammer into a mouthful locating aperture in a kind of bone surgery the marrow being invaded by pathogen and insert guide pin system.
Background technology
In bone surgery, Medullary fixation is extensive use, intramedullary pin internal fixtion has the rule of operation of complete set, but intramedullary pin entrance is established a capital really does not have apparatus to help, the whether accurate quality that decide operation of entrance, although and the selection of entrance has clear and definite regulation, opening can be carried out insert guide pin in the narrow regions of regulation, manifest the technical ability of orthopedist individual, but due to patient size different; Type of fracture varies, even if time the most experienced orthopedist also makes opening depart from normal region, gently then reduce surgical effect; Heavy then operation falls flat.
In the interchange of orthopedist colleague, the effect of most intramedullary pin internal fixation operation is only close to or relatively fixes close to satisfied in fact.Wherein enter to follow closely opening whether completely satisfaction occupy significant proportion, especially young doctor is needed to the learning curve grown very much, and opening correctly guide pin to be inserted pulp cavity after completing be an experiential operating, operation afterwards is then completed by intramedullary pin and subsidiary tool guides thereof; Relatively surgical quality can be ensured.
And the device that the intramedullary pin that current each bone surgery set supplier provides all does not have opening to locate, although opening is very important, orthopedist is still needed to determine by rule of thumb for intramedullary pin aperture position, therefore, the operation of same type is because of patient's difference, and fixed mass difference is very large.And intramedullary pin opening location is put guide pin system fast and can be addressed this problem well, after using intramedullary pin opening location to put guide pin system fast, can ensure that the opening of intramedullary pin is opened in the region instructed at apparatus used by young orthopedist, and guide pin is inserted pulp cavity simultaneously, during shortening operation, improve surgical quality.
Through the literature search author Li Bo etc. of prior art at document " femoral shaft and intertrochanteric fracture Intramedullary nailing proximal openings observation of curative effect " Hebei medicine, 2009,07:1811 mentions " by touching tuberosity determination near-end otch at body surface; look for entry point; we find tuberosity location often difficulty; particularly abecedarian, is difficult to accurate assurance ". proposes a kind of PFN opening locating assist system but this apparatus can solve the control that intramedullary pin opening is in medial and lateral, greater trochanter summit through patent retrieval author Ji Liefeng etc. in patent " PFN opening locating assist system " number of patent application 2013207416023 publication number CN203539428U , and opening problem to the front, to the rear can not be controlled, repeatedly need hole and select most suitable guide pin, therefore, if [0022] is for ease of boring multiple locating hole, described guide hole 11 has 6.And this apparatus is to be positioned at inside opening part part volume excessive, normal intramedullary pin otch cannot insert this apparatus, and blocking due to proximal tissue, opening leads brill cannot enter pulp cavity.
Summary of the invention
In order to overcome the deficiency of existing apparatus, when not increasing patient's soft tissue injury, insert location, guide instrument, disposable brill of leading pierces pulp cavity in intramedullary pin opening regulation region, greatly improve procedure efficiency, reduce patient's wound open-assembly time, reduce operation risk.The invention provides a kind of intramedullary pin opening location and put guide pin system fast, can make abecedarian correctly at intramedullary pin entry point opening, and guide pin is directly inserted pulp cavity, structure of the present invention is simple, easy to use, successful, workable and easy to implement.
There is provided a kind of intramedullary pin opening location to put guide pin system fast according to an aspect of the present invention to comprise " L " type guide handle, encircle pin, outer needle, lead brill guide sleeve, wherein
Described leading bores the top that guide sleeve is positioned at described " L " type guide handle transverse arm, make to lead that to pierce direction consistent with the long-armed direction of guide handle, described guide handle transverse arm is closely led and is bored side, guide sleeve place two and be provided with and encircle pin, the long-armed near bending part of described guide handle is provided with outer needle hole, and described outer needle is connected with the long-armed of described guide handle by screw thread.
Described lead bore guide sleeve, outer needle, two side rings embrace pin by needing on opening part epiphysis, outer, forward and backward four sides encircles, the long-armed adjustment guide sleeve of guide handle pierces direction, and so, opening leads the entrance of brill and direction is fixed.
First outer needle is unloaded when first intramedullary pin opening location being put guide pin system sterilizing use for subsequent use fast before using, conventional transdermal otch, cut skin and subcutaneous tissue, to point detection sclerotin edge, intramedullary pin porch, insert intramedullary pin opening location and put guide pin system fast, two side rings are embraced before pin lays respectively at sclerotin, trailing edge, distally pressing makes to lead and bores guide sleeve close to opening part cortical bone, outer needle is installed, outer needle is made to withstand outside sclerotin, regulate the long-armed of guide handle, make it consistent with left and right directions with before and after long bone pulp cavity, firmly withstand guidance system opening part, lead brill and namely bore guide sleeve boring opening by leading, and pierce to deep and directly can enter pulp cavity.Unload outer needle, intramedullary pin opening location is put guide pin system fast and can be exited from leading brill, completes intramedullary pin guide pin and is placed into work.
of the present invention only has 2 separating components composition due to apparatus, and use simple to operate, reliability is high, and apparatus is provided with the caster assembly therefor consistent with pulp cavity direction, can make to pierce to lead to bore directly to enter pulp cavity by opening part, has greatly saved the time that placement guide pin spends.
