Description

Surgical forceps

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a pair of surgical forceps.

Background

In general, surgical instruments (including forceps) can be classified as single-use instruments, such as those that are discarded after a single use; a partially reusable instrument, such as an instrument comprising a disposable portion and a portion sterilized for reuse; and wholly reusable instruments, such as instruments that are wholly sterilized for reuse. As can be appreciated, instruments (or instrument components) that can be sterilized and reused help reduce costs associated with the surgical procedures used.

The existing surgical forceps are scissor-type surgical forceps, one end of each surgical forceps is a handheld part, the other end of each surgical forceps is a clamping part, the clamping parts are generally flat for facilitating clamping, manual control force is applied during surgery, tumors or disease variants and the like are clamped through the clamping parts, and then the operation is performed.

Most surgical forceps are currently reusable forceps, and because of the high cost, it is highly necessary to use reusable forceps in order to save costs; however, the use habit and the hand size of different users are different for the forceps of the same model; therefore, surgical forceps of different models and sizes need to be purchased to meet different operators, wherein forceps handles of different lengths need to be adopted for surgery according to the use condition of patients or doctors, and meanwhile, due to the size of hands and the use habit of the doctors, different opening degrees between the two forceps handles in a closed state need to be replaced, so that the forceps are convenient for the doctors to use.

And in some occasions, in order to save unnecessary cost, a surgical forceps capable of adjusting the length of a handle is needed, for example, when a doctor or a nurse performs practice, due to limited cost of some schools or hospitals, hands of each person are different for a large number of students or doctors, and the practice needs to purchase the surgical forceps with different sizes according to the sizes of hands to meet the requirement, so that money and money are wasted greatly.

For the surgical forceps described in the patent number CN213310115U in the prior art, the problem that the length of the forceps handle can be adjusted at any time in the operation by setting the handle rod of the handle to be a structure capable of adjusting the length is mainly solved, and the applicability is stronger. The detachable surgical forceps for the obstetrics and gynecology department disclosed by the prior art patent number CN113893003A mainly solves the problems that the operation of forceps tips is realized through a lever principle in the use process of the conventional detachable surgical forceps for the obstetrics and gynecology department, but because the length of a forceps handle is fixed, medical staff needs to apply the same external force all the time to operate, the tiredness degree of the medical staff is increased, and the functionality of the surgical forceps is reduced. Although the above prior art can adjust the length of the clamp handle, the structure is complicated and the adjustment is inconvenient.

In order to solve the problems, the surgical forceps provided by the utility model can change the opening degree between two forceps handles in the closed state of the forceps head and can adjust the distance between the forceps handles and the forceps head.
