Abstract

The utility model discloses a latex tube with a lock-out hasp used for blocking hepatic portal bloodstream. The hasp latex tube comprises a lock-out hasp and a latex tube, wherien, the left side surface of the lock-out hasp adopts an elastic arc-shaped structure; a row of protrusions perpendicular to the inner side of the lock-out hasp are formed on the right side surface of the lock-out hasp; when the protrusions are tightly clamped on the upper side surface, the latex tube is locked out; two small holes, through which the latex tube penetrates, are formed on the left side surface of the lock-out hasp as well as on the right side surface thereof; two rows of correponding protrusions are formed on the inner sides of the upper side surface and a bottom surface respectively; and when the lock-out hasp is locked out, the protrusions on the upper side surface and the bottom surface are just tightly clamped on the latex tube. The utility model simplifies hepatic portal bloodstream blocking procedure, improves hemostatic effect, has a broad application prospect.

Description

A kind of be used for the hepatic portal bloodstream blocking carry enclosed type hasp latex tubing

Technical field

This utility model belongs to medical instruments field, more specifically, is used for the medical apparatus and instruments of anus blocking-up when relating to a kind of hepatocarcinoma surgical operation.

Background technology

Often need method control hepatorrhagia in the hepatectomy with hepatic portal occlusion, its method is that the free earlier patient of cut-out liver is about all ligaments and adhesion organization, tighten hepatoduodenal ligament with a latex tubing then, and with one little blunt nosed mosquito forceps is clamped latex tubing and prevent to get loose in the excision process, make liver be in ischemic state, come into effect hepatectomy subsequently.

This method has following defective: the broadband of (1), hepatoduodenal ligament is also inconsistent, broad for the overweight people, and the open maximum angle of mosquito forceps is limited, like this in blocking-up, tend to occur mosquito forceps and can't press close to ligament as far as possible and carry out clamp, thereby cause haemostatic effect not good.(2), clamp latex tubing with mosquito forceps, need to guarantee that the pincers point can not exceed tube wall, in order to avoid important structure around when operation technique, accidentally injuring, but the space of art open country is limited, to finish these technical movements rapidly accurately, for the abecedarian or owe to be difficult to hold at short notice technical key point for the practician.(3), after mosquito forceps clamps, before beginning, hepatectomy needs the pincers handle is placed intraperitoneal below the otch, with obstruction free operation subsequently.And for the patient of abdominal repeatedly, may there be more adhesion in its intraperitoneal, and the pincers handle is inserted difficulty or caused that unnecessary tissue accidentally injures.

The utility model content

The technical problems to be solved in the utility model provides a kind of simplification hepatic portal bloodstream blocking program, and that improves haemostatic effect carries enclosed type hasp latex tubing.

For solving the problems of the technologies described above, this utility model provide a kind of be used for the hepatic portal bloodstream blocking carry enclosed type hasp latex tubing, comprise locking hasp and latex tubing, there is a projection described locking hasp side, block the capable locking of firm upper side, two sides respectively have two apertures to pass for latex tubing, and during the locking of locking hasp, the triangular shape projection of upper side and the projection of bottom surface are blocked firm latex tubing just.

This utility model has overcome with the existing deficiency of mosquito forceps, adopts the locking hasp with the latex tubing locking, assists cover to prick hepatoduodenal ligament.Have two rounds on the blocking device, after insert respectively at the latex tubing two ends, between pipe and blocking device, form a circulus, with the ligament cover inside, tighten up pipe, and locking device is slided in the opposite direction, tighten ligament.Can guarantee the definitiveness and the effectiveness of hepatic portal occlusion like this, reduce influence again limited art open country.Operation is upward simple in addition, and the abecedarian grasps easily.

Description of drawings

Below in conjunction with drawings and embodiments this utility model is described in further detail.

Fig. 1 is the front view that this utility model does not insert latex tubing.

Fig. 2 is the front view that this utility model inserts latex tubing.

Fig. 3 is the right view that this utility model does not insert latex tubing.

Fig. 4 A, 4B are the axonometric charts in this utility model user mode, and Fig. 4 A is a locking hasp opening, and Fig. 4 B is a locking hasp closed condition.

Wherein, 1 is upper side triangular shape projection, and 2 is the bottom surface projection, and 3 is the right flank projection, and 4 is the inclined-plane at upper side edge, and 5 is the left surface aperture, and 6 is the right flank aperture, and 7 is latex tubing, and 8 are the locking hasp, and a side of pointing to locking hasp inside is called " inboard ".

The specific embodiment

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, this utility model comprises locking hasp 8 and latex tubing 7, locking hasp 8 is made up of upper side, bottom surface, right flank and four faces of left surface, left surface is for having certain elastic arcuate structure, right flank has the inboard with it vertical projection 3 of a row, closed with upper side edge card jail row, there is an inclined-plane 4 at the upper side edge, and resistance reduces when making toward descending locking; Latex tubing 7 is free to penetrate

aperture

5,6, and during the row locking, the vertical with it projection 1 of the inboard row of the upper side projection 2 corresponding with bottom surface one row blocked the jail with latex tubing 7 just.In the present embodiment, projection 1 is triangular shape, and projection 2 is the convex arcuation.

Latex tubing 7 internal orifice dimensions are 0.5cm, and length is 30cm; Locking hasp 8 is locking, unlatching repeatedly.When locking hasp 8 is in opening, after penetrating, latex tubing 7 can be free to slide.

In operation, at first block preceding preparation, being about to latex tubing 7 one ends passes from a round of locking hasp 8, and folder locking hasp 8, pass through from the hepatoduodenal ligament below according to the other end of traditional method then latex tubing 7, next step opens locking hasp 8, and latex tubing 7 other ends are passed (shown in Fig. 4 A, 4B) from another round of locking hasp 8.After finishing above-mentioned steps, can tighten up latex tubing 7, and locking hasp 8 is slided to the hepatoduodenal ligament direction, locking at once to the appropriate location is finished hepatic portal occlusion.

If operation need just can be finished by hepatic portal occlusion repeatedly, the step that repeats " decontrol snap close-tighten up latex tubing-locking hasp " gets final product.

This utility model is not limited to above-mentioned embodiment; no matter on its shape or structure, do any variation; every device that utilizes latex tubing to pass the capable hepatic portal occlusion of locking hasp all drops in this utility model protection domain; be not limited to two rows such as the aperture on the locking hasp at least two rows; be used to block the upper side of latex tubing and the thrust shape of bottom surface also is not limited to embodiment, the size of latex tubing, length can adjust according to actual needs.
