Abstract
The invention relates to a surgical incision distracting device having a pressure display function. The surgical incision distracting device comprises a rotary supporting plate, wherein the rotary supporting plate is provided with a boss, a rotary rod is rotatably arranged the boss in a penetrating mode, a handheld wheel is arranged at the upper end of the rotary rod, and a gear is fixedly connected to the lower end of the rotary rod. Distracting plates are symmetrically arranged on the lower surface of the rotary supporting plate and comprise outer supporting plates arranged in a staggered mode and inner racks meshed with the gear, and the ends of the outer supporting plates are provided with upper distracting ends and lower distracting ends which are arranged vertically. The upper surfaces of the inner racks are provided with sliding flanges, and chutes in sliding fit with the sliding flanges are formed in the two sides of the lower surface of the rotary supporting plate. The surgical incision distracting device further comprises a pressure gauge arranged on the upper surface of the handheld wheel, and the pressure gauge is connected with the gear. The surgical incision distracting device is simple in structure, simple and convenient to operate and high in use reliability.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to the dilator in general surgery.
Background technology
At present, adopt multiple drag hook to be pulled open at operative incision position in general surgery, facilitate medical operating to broaden one's vision, need multiple medical personnel to cooperate.Adopt drag hook type to strut the shortcoming of operation obviously, medical personnel are long-time easily tired, make troubles to operation.For solving the problem, have the dilator adopting two ends to pull locking positioning, this dilator can strut width according to the size adjustment of operative incision, hand-held for a long time without the need to medical personnel, but its deficiency existed is: when being pulled laterally at two ends, easily strut owing to operating inconvenience excessive, damage is caused to operative incision; Support force deficiency when the crotch at two ends props up notching edge causes dilator to fall, and struts mouth and reduces, affect operation technique.
Summary of the invention
The above-mentioned shortcoming that the applicant exists for prior art, carries out studying and designing, and provides a kind of operation otch device for spreading with pressure display, and it has, and easy to operate, structure is simple, service-strong feature.
The technical solution adopted in the present invention is as follows:
With an operation otch device for spreading for pressure display, comprise rotary support plate, with boss on rotary support plate, running through tumbler in described boss has bull stick, and the upper end of described bull stick is taken turns with hand-held, and its lower end is connected gear; The relatively described gear centre symmetrical mounting of lower surface in described rotary support plate has distraction plate, described distraction plate comprises the outer fagging and inner rack with described gears meshing that stagger and arrange, the end of described outer fagging with strut on setting up and down end and under strut end; The upper surface of described inner rack is with slip flange, and the lower surface both sides of described rotary support plate are provided with the chute be slidably matched with described slip flange;
This device also comprises and is installed on described hand-held Pressure gauge of taking turns upper surface, and described Pressure gauge is connected with described gear.
Further improvement as technique scheme:
On described bull stick, screw has the lock sleeve be positioned at above described boss.
Beneficial effect of the present invention is as follows:
The present invention compares the dilator of pull type, and it adopts rotating manner, is convenient to the adjustment to strutting width, to the damage of operative incision when avoiding strutting excessive; Locking sleeve structure is set, the convenient locking operation to distraction plate; What adopt Dual-layer struts end, avoids dilator to fall, and improves the reliability used; The size that Pressure gauge facilitates medical personnel to observe to strut pressure is set.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the operation otch device for spreading of the band pressure of the present embodiment display, comprise rotary support plate 1, with boss 11 on rotary support plate 1, running through tumbler in boss 11 has bull stick 3, and the lower end of bull stick 3 is connected gear 5; Lower surface opposed gear 5 centrosymmetry device in rotary support plate 1 has distraction plate 2, distraction plate 2 comprises the stagger outer fagging 21 arranged and the inner rack 22 engaged with gear 5, the end of outer fagging 21 with strut on setting up and down end 24 and under strut end 23, strut the edge clamping operative incision between end up and down, prevent dilator from falling to causing to support openings get smaller.
As shown in Figures 3 and 4, the upper surface of inner rack 22 is with slip flange 25, and the lower surface both sides of rotary support plate 1 are provided with the chute 12 be slidably matched with the flange 25 that slides.
For ease of the rotating operation to bull stick 3, the upper end of bull stick 3 takes turns 4 with hand-held, hand-held take turns 4 with bull stick 3 can be made into integrative-structure, also can form spiral with bull stick 3 and be connected, with for convenience detach; Hand-held upper surface device of taking turns 4 has Pressure gauge 7, and Pressure gauge 7 is connected with gear 5, for the rotation torque magnitude of detection of gear 5.
On bull stick 3, screw has the lock sleeve 6 being positioned at boss 11 side, and lock sleeve 6 prevents it from reversing for locking bull stick 3.
When the present invention uses, rotate and hand-heldly take turns 4, gear 5 rotates and drives the inner rack 22 of both sides to move to two ends, namely outer fagging 21 moves to two ends and is strutted by operative incision, and makes the edge strutting end clamping operative incision up and down, when reaching required width, continue slightly to stir and hand-heldly take turns 4 and observe the pressure size of Pressure gauge 7, when reaching convenient pressure, rotation lock cover 6, locks bull stick 3 after lock sleeve 6 and boss 11 push against, prevents it from reversing.
The present invention compares the dilator of pull type, and it adopts rotating manner, is convenient to the adjustment to strutting width, to the damage of operative incision when avoiding strutting excessive; Locking sleeve structure is set, the convenient locking operation to distraction plate; What adopt Dual-layer struts end, avoids dilator to fall, and improves the reliability used; The size that Pressure gauge facilitates medical personnel to observe to strut pressure is set.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
