Description

Suitable for the dedicated hose expander of surgical operation

Technical field

The utility model is related to medical auxiliary apparatus, are suitable for the dedicated hose of surgical operation more particularly, to one kind and expand Device.

Background technology

In surgery clinical operation, the operation by large-caliber hose and thin and flexible tube socket is frequently run onto, especially in liver The operation of the T pipes socket drainage bag of the postoperative indwelling of common Patients with Cholelithiasis in courage surgery, the bile in T-shaped Tube Drain cavity, To mitigate the pressure of bile duct.T-shaped pipe is a kind of rubber tube of bore very little, the both ends of T-shaped pipe transverse part respectively with bile duct one The broken ends of fractured bone is connected, and the outlet end of T-shaped pipe vertical portion is extended outward external and is connected with drainage tube.It is used currently without special In the expander for expanding T-shaped pipe or drainage tube, the connection method of existing T-shaped pipe and drainage tube is to utilize vessel forceps or tweezers by T Shape pipe nozzle struts, and then bigbore drainage tube is inserted into T-shaped pipe again, and since T-shaped pipe caliber is small, vessel forceps or Tweezers insertion is difficult, and entire connection procedure needs two medical staff, and operating process is cumbersome, and operating time is long, increases sufferer quilt The risk of infection；Further, since it is inconvenient, also easily there is the phenomenon that drawing T-shaped pipe vertical portion, increase the pain of sufferer Sense, also results in T-shaped pipe and deviates from out of body cavity and form anastomotic leakage when serious.

The content of the invention

The utility model aim is to provide a kind of suitable for the dedicated hose expander of surgical operation, hose expander behaviour Facilitate, can effectively reduce the hose Connection Time, reduce the infected probability of sufferer.

To achieve the above object, the utility model takes following technical proposals：

Described in the utility model to be suitable for the dedicated hose expander of surgical operation, including caliper, the caliper includes first Tong arm and the second tong arm, first, second tong arm are integrated by hinge shaft hinge, and the binding clip portion of first tong arm is vertically set It is equipped with the first arc expansion board, the binding clip portion of second tong arm is vertically installed with the second arc expansion board, and described first, second The one side of arc expansion board top margin has been extended connecting rod, and external screw thread, first, second tong arm point are provided in the connecting rod It is offered on not and passes through connecting rod and the first tong arm screw thread with the matched internal thread of connecting rod external screw thread, the first arc expansion board Connection, the second arc expansion board are threadedly coupled with the second tong arm；The first, second arc expansion harden structure is identical and correspondence is set It puts, interior receipts, the edge of first, second arc expansion board bottom are equal from top to bottom for the two sides of first, second arc expansion board For arcuate structure, the shape after the expansion of first, second arc expansion board is in the triangular structure or sector that bottom is arcuate bottom Structure；

The bottom of first, second tong arm is both provided with finger ring, is connected on the first tong arm of the hinge shaft lower part There is locking rack, be fixed on the second tong arm and the matched lock of the locking rack.

The utility model advantage is simple in structure, first, second arc expansion board is inserted into hose during use and will Hose struts, and locking rack and lock have locking effect, it is ensured that the expansion aperture of first, second arc expansion board, it is only necessary to one The grafting operation of two hoses can be completed in name medical staff, easy to operate, effectively shortens the grafting time, effectively shortens sufferer body cavity Exposure duration, reduce the probability of sufferer body cavity infection；In grafting, can before choleresis by endoceliac hose with it is outer It is connected with drainage tube, is further reduced the probability of retrograde infection.

Specific embodiment

As shown in Figure 1, described in the utility model be suitable for the dedicated hose expander of surgical operation, including caliper, caliper bag The first tong arm 1 and the second tong arm 2 are included, first, second tong arm 1,2 is integrated by the hinge of hinge shaft 3, the binding clip portion of the first tong arm 1 It is vertically installed with the first arc expansion board 4, the binding clip portion of the second tong arm 2 is vertically installed with the second arc expansion board 5, and first, Two arc panels 4,5 structures are identical and are correspondingly arranged, as shown in figure 3, the two sides of first, second arc expansion board 4,5 are from upper And lower interior receipts, and first, second arc expansion board 4,5 bottoms are arcuate bottom, the expansion of first, second arc expansion board 4,5 Shape afterwards is arcuate bottom sector structure in bottom, as shown in Fig. 2, being in rounding when first, second arc expansion board 4,5 is engaged Pyramidal structure, and the bottom of the inverted conical structure is arcuate bottom（Certainly, first, second arc expansion board during actual manufacture 4th, the shape after 5 expansion can also be the triangular structure that bottom is arcuate bottom, at this point, first, second arc expansion board 4,5 is stung The figure that its top margin surrounds during conjunction is in circular ring shape）, it is distracted soft convenient for first, second arc expansion board 4,5 is inserted into needs In pipe；

The bottom of first, second tong arm 1,2 is both provided with finger ring 6, solid on the first tong arm 1 of 3 lower part of hinge shaft Locking rack 7 is connected with, is fixed on the second tong arm 2 and the matched lock 8 of the locking rack 7, locking rack 7 and lock 8 It cooperates, it can be ensured that the expansion aperture of first, second arc panel 4,5 does not change in two hose grafting, a doctor Hose grafting can be completed in shield personnel, saves labour, improves work efficiency.

During actual manufacture, there are many specification, first, second arc expansion boards 4,5 for first, second arc expansion board 4,5 The one side of top margin has been extended connecting rod, is provided with external screw thread in connecting rod, first, second tong arm 1,2 respectively on offer With the matched internal thread of connecting rod external screw thread, the first arc expansion board 4 is threadedly coupled by connecting rod with the first tong arm 1, the Two arc expansion boards 5 are threadedly coupled with the second tong arm 2, are conveniently replaceable first, second arc expansion board 4,5, to meet actual behaviour Make demand.

In use, first carrying out disinfection to the present apparatus, hose, then medical staff picks up thin and flexible tube, by first, second Arc expansion board 4,5 is inserted into hose and struts the hose, and the degrees of expansion for making first, second arc expansion board 4,5 is big In the bore of hose waiting, then by 8 locking of locking rack 7 and lock, it is ensured that first, second arc expansion board 4,5 can be protected Hold the open configuration, medical staff takes expander on the other hand, the other hand by hose waiting be inserted into first, second arc expansion board 4, In gap between 5, first, second arc expansion board 4,5 is extracted after being inserted into certain depth；According to actual need Will, replacing first, second arc expansion board 4,5 of different size makes it be engaged with the hose that needs are expanded, convenient for expansion.
