Problems solved by technology

[0004] In the process of axillary lymph node dissection, more medical staff need to use retractors to expose the surgical field of view. The control of the retractors does not require high operational skills, it is only simple physical labor, and the entire operation process is relatively long. On the one hand, Occupies more medical staff, resulting in a waste of medical resources. On the other hand, more medical staff also squeezes the space of the operating room

Embodiment 1

[0033] Such as Figure 1-5 Shown: a retractor for lymph node dissection in breast-conserving surgery, including retractor head 1, retractor handle 2, elastic stretchable part 3 and locking component 4, retractable hook head 1 is used for pulling the patient's muscles, and elastic stretchable part 3 can be elastic A spring of appropriate size can make the pulling force become a non-rigid force, avoiding the damage of muscle tissue caused by hard pulling. The function of the locking component 4 is to adjust the size of the opening of the hook. The component 4 locks the muscle tissue and the draw hook head 1 together to prevent the muscles from detaching from the draw hook head 1 . The hook head 1 is a "J"-shaped structure integrally formed by the long rod part 1-1, the connecting rod part 1-2 and the short rod part 1-3, and the free end of the short rod part 1-3 is connected to the A hook opening is formed between them, the tail end of the hook handle 2 is provided with a hook ...

Embodiment 2

[0037] Such as Figure 6-8 Shown: a retractor for lymph node dissection in breast-conserving surgery, including retractor head 1, retractor handle 2, elastic stretchable part 3 and locking component 4, retractable hook head 1 is used for pulling the patient's muscles, and elastic stretchable part 3 can be elastic A spring of appropriate size can make the pulling force become a non-rigid force, avoiding the damage of muscle tissue caused by hard pulling. The function of the locking component 4 is to adjust the size of the opening of the hook. The component 4 locks the muscle tissue and the draw hook head 1 together to prevent the muscles from detaching from the draw hook head 1 . The hook head 1 is a "J"-shaped structure integrally formed by the long rod part 1-1, the connecting rod part 1-2 and the short rod part 1-3, and the free end of the short rod part 1-3 is connected to the A hook opening is formed between them, the tail end of the hook handle 2 is provided with a hook ...

Embodiment 3

[0041] Such as Figure 9-10 Shown: a retractor for lymph node dissection in breast-conserving surgery, including a retractor head 1, a retractor handle 2, an elastic stretcher 3, a locking component 4 and a light source component 5, the retractor head 1 is used for pulling the patient's muscles, and the stretchable stretcher 3. A spring with appropriate elastic force can be selected to change the pulling force into a non-rigid force to avoid muscle tissue damage caused by hard pulling. The function of the locking component 4 is to adjust the size of the opening of the pull hook. After the pull hook head 1 hooks the muscle , the muscle tissue and the retractor head 1 are locked together by the locking component 4 to prevent the muscles from detaching from the retractor head 1 . The hook head 1 is a "J"-shaped structure integrally formed by the long rod part 1-1, the connecting rod part 1-2 and the short rod part 1-3, and the free end of the short rod part 1-3 is connected to th...

Abstract

The invention relates to a lymph node dissection wire retractor and a dissection auxiliary device for a breast conservation surgery. The dissection wire retractor comprises a wire retractor head, a wire retractor handle, an elastic expansion part and a locking component, wherein the wire retractor head has a J-shaped structure which is integrally formed by a long rod part, a connecting rod part and a short rod part, and a wire retractor opening is formed between the free end of the short rod part and the long rod part; the locking component is used for adjusting the size of the opening of thewire retractor. The auxiliary device comprises a wire retractor fixing rack and a plurality of dissection wire retractors, wherein the wire retractor fixing rack comprises a base, an upright tube, twocross bars and two hooking rods. The lymph node dissection wire retractor has a function of adjusting the opening, the opening of the wire retractor can be reduced through the locking component aftermuscle is hooked by the wire retractor, and the muscle is prevented from separating from the wire retractor. The auxiliary device has the cross bars and hooking rods, which can be expanded, various fixing modes can be provided to the dissection wire retractor through different expanding angles of the cross bars and hooking rods, so that the requirement during a surgery can be met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lymph node cleaning hook and cleaning auxiliary device for breast-conserving surgery. Background technique [0002] There are many effective treatment methods for breast cancer, but surgery is recognized as the basis of breast cancer treatment, and radical surgery is still the most important surgical treatment for breast cancer patients. Axillary lymph node dissection is an important part of radical mastectomy and modified radical mastectomy. The fundamental purpose of axillary lymph node dissection is to clarify the metastatic status of axillary lymph nodes of breast cancer, prevent local recurrence of breast cancer in the axillary and improve the survival rate of patients as much as possible. [0003] Subaxillary lymph node dissection is mainly suitable for patients with early-stage tumors and negative lymph nodes in clinical physical examination. Dissection of the ...
