Description

Hepatic portal vein blood vessel drag hook

Technical field

This utility model relates to a kind of medical operation assistive device, specifically is meant a kind of blood vessel drag hook.

Background technology

The vein blood vessel puncture technique is widely used clinically, in treatment disease and redemption life, brought into play important effect, in the operation, because the hepatic portal vein blood vessel is tiny, therefore difficulty is looked in operation in degree of depth body, or after finding, in operation, shrink back again easily, cause operation to carry out smoothly, when seeking vein blood vessel again, spent again some times simultaneously, prolonged the time of whole surgery, also can therefore cause sometimes to make patient miss best treatment time.

In addition owing to need epidermis is severed in the operation, the epidermis that so also needs to cut unplugs gently, the present traditional operation drag hook that uses, owing to be subjected to the restriction of its mechanical form, and be difficult to satisfy the needs of the various different operating field depths, can cause blood loss many, increased patient's misery, be unfavorable for the recovery of health, and the wound that causes to body surface is excessive, influences attractive in appearance.

The utility model content

The purpose of this utility model is to provide a kind of surgery instrument simple in structure, easy to use, especially in hepatic portal vein operation, can protect minute blood vessel and neural preserve from hepatic portal vein blood vessel drag hook.

For achieving the above object, technical solution of the present utility model is:

A kind of hepatic portal vein blood vessel drag hook comprises that C type hook, column type connect rod and handle, and C type hook connects rod by column type and connects with the hands tenon is vertical, and C type hook and hands tenon connect rod with column type center is on same straight line.

Described C type hook for from bottom to top 30 the degree rear arc, the afterbody of described hook also is provided with the overhead kick arc.

Described C type hook is a sector structure, and described afterbody at C type hook is provided with barb.

Described handle is provided with the waveform radian.

After adopting such scheme; this utility model is because the hepatic portal vein blood vessel drag hook that adopts C type hook, column type connection rod and handle to link and form; it is simple in structure; easy to use and safety, and adopt afterbody to be provided with barb at C type hook, it can more effectively hook minute blood vessel; play a protective effect; or the skin that surgical cut is opened drawn back, especially in degree of depth body, in the operation, minute blood vessel or nerve are played a protective role.In addition, be provided with the waveform radian on handle, when handing, its finger just is held in the waveform position, and it can increase frictional force, makes that the patient that damages is not avoided in slippage easily, and its nerve is preserved from operation is used.

The specific embodiment

Embodiment one:

A kind of hepatic portal vein blood vessel drag hook 1, shown in Fig. 1-2, comprise C type hook 11, column type connects rod 12 and one handle 13, C type hook 11 connects rod 12 and 13 vertical connections of hands tenon by column type, during connection, C type hook 11 and hands tenon 13 connect the center of rod 12 on same straight line with column type, guarantee that hepatic portal vein blood vessel drag hook 1 is stressed even, described C type hook 11 be from bottom to top 30 the degree rear arc, its afterbody at hook also is provided with barb arc 111, can effectively catch on tiny blood vessel during use, makes the minute blood vessel can landing.Described handle 13 is provided with waveform radian 131, and when handing, its finger just is held in the waveform position, and it can increase frictional force, makes that not slippage is easily avoided causing the accident in operation is used.

Embodiment two:

A kind of hepatic portal vein blood vessel drag hook 2; as shown in Figure 3-4; comprise C type hook 21; column type connects rod 22 and one handle 23; C type hook 21 connects rod 22 and 23 vertical connections of hands tenon by column type; during connection; C type hook 21 and hands tenon 23 connect the center of rod 22 on same straight line with column type; described C type hook 21 is to be a sector structure; its top 211 that C type hook 21 is is less than the sector structure of the bottom 212 of C type hook 21; can reduce the contact area of C type hook 21 and operative site skin when using like this, be protected the patient.In addition, also be provided with overhead kick 213 at the afterbody of C type hook 21, it can better catch on tiny blood vessel in use, makes the minute blood vessel can landing.It is identical with handle 13 with embodiment one described column type connection rod 12 with handle 23 that the described column type of present embodiment connects rod 22, and handle 23 also has been provided with waveform radian 231.

Above embodiment is only for the usefulness that this utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, as the handle of hepatic portal vein blood vessel drag hook or the profile of connection rod are made simple change, therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
